C-KIT DOOR building Toolkit Library Version 2.10 Reference Manual Distributed By Data-Comp Information Systems P.O. Box 5895 Maryville, Tenn. 37802-5895 (615) 982-6537 (Hayes Ultra V.32, public line) (615) 982-8723 (Hayes Ultra V.32, private line) (615) 982-6512 (USR HST Dual Standard V.32, private line) (615) 970-7418 (USR HST Dual Standard V.32, private line) Copyright (c) 1989, 90, 91 Rickie W. Belitz Introduction Introduction C-KIT Library is an extensive library of C runtime routines that allow easy door program implementation using PCBoard 12.0 through 14.x, WILDCAT! systems, (all versions), GAP BBS, SPITFIRE BBS 3.0 and other systems using standard DOOR.SYS file along with RBBS-PC, QuickBBS, Remote Access and other systems using DORINFOx.DEF files. C-KIT 2.01 will also work properly with MikeBBS (MBBS) v9.9 and above. CKIT will automatically work with the above system. For systems not listed above, CKIT can deal with them in one of two ways. CKIT can utilize a file called GENERIC.SYS. This is for creating a system file for a system CKIT does not support. See section on GENERIC.SYS for more information. In addition, CKIT will also accept a pointer to a structure that contains the needed information for CKIT to operate. This could be the result of your program reading ANY BBS's system file. This structure will allow C-KIT to work on ANY BBS system, providing the door author reads the BBS file himself. Some other C-KIT Library's features include interrupt driven I/O, 16550AN UART support, FOSSIL support, provides information available from the PCBoard .sys files, database files, multi-node support (file sharing), multi-BBS support, local sysop function keys and many more utilities are included for the door author. The C-KIT Library routines are written entirely in Assembly language using SLR's Optasm. The routines make use of C library functions when possible and are compatible with Microsoft C, Microsoft QuickC, TURBO C, and TURBO C++. C-KIT Library supports the small, medium and large models. Microsoft is a registered trademark, and QuickC is a trademark of the Microsoft Corporation. TURBO C is a registered trademark of Borland International Inc. TURBO C++ is a registered trademark of Borland International Inc. PCBoard is a registered trademark of Clark Development Company. WILDCAT! is a registered trademark of Mustang Software. SPITFIRE is a registered trademark of Buffalo Creek Software RBBS-PC is copyright (c) Tom Mack, Capital PC Software Exchange QUICKBBS is copyright (c) Adam Hudson REMOTE ACCESS is copyright (c) Andrew Milner, Continental Software MBBS is copyright (c) Mike Anderson Registration The unregistered library will display "Unregistered copy etc." as part of the signoff message. The registered version eliminates this signoff msg at the time the door is closed. Please see the registration information below. A lot of effort has gone into C-KIT, to make sure it would operate reliably and with little effort on the part of the door author. If you find the program of use, please register it and help support the Shareware method of program distribution. Registering will also help fund further development of the libraries. C-KIT is being distributed as Shareware. The registration includes: ∙ A disk with the latest version of C-KIT, registered to you. . Some small utility programs for easy door testing w/source. ∙ Self-Registration program for future releases of C-KIT ∙ Technical support via electronic mail . A LARGE memory model of C-KIT. (download from Data-Comp BBS) (The LARGE model will also work as a HUGE model) . Access to source code for reading other system files as they become available. All PCBoard source files are now available. For more information see the addresses, phone numbers listed at the end of this document. Global Variables Global Functions/Variable Naming Conventions The C-KIT Library defines a number of variables and functions in the c-kit header file. These have to be made public for the linker to be able to resolve references to them. Beginning in C-KIT 2.0 ALL functions/variables available from the library begin with the prefix "ck_". This will help prevent any naming conflicts with other globals in your source code. Knowing that all C-KIT's names begin with "ck_", you can prevent any collisions with the public names contained in the library. If this is of little concern to you or if you do not like the names used in the library because of this, then you can simply re-define the names to any name you desire. OLDCKIT.H does exactly this for previous users of the library. OLDCKIT.H re-defines the new names to the old names used in the library. If you included OLDCKIT.H in your present source code, then the new library names would work with no other changes to your present source code. Example: Name desired Library Name ======= =========== ============ #define s_puts ck_s_puts #define DUMP_USER ck_DUMP_USER #define color ck_color #define newline ck_newline #define get_cmdline ck_get_cmdline These would cause the compiler to reference the new name for all references to old name. do { color(green); s_puts("Command? ", NULL); get_cmdline(); /* read input into 'cmdline' */ newline(); } while( (DUMP_USER != TRUE) && ( strlen(cmdline) == 0 )); See OLDCKIT.H and CKITDEMO.C, CKITDEMO.H. NOTE: The ONLY variable that does not have the "ck_" prefix is the progname[]; array name in the CKIT.H file. Global Variables Global Variables used by all BBS systems The C-KIT Library defines a number of variables in the ckit.h header file. Through proper use, these variables allow the programmer to customize the C-KIT Library functions to meet particular application program's needs. ck_DUMP_USER ------------------------------------------------------------------- Defined As: short ck_DUMP_USER; Description: This variable will be set if the user hangs up, his/her time runs out, carrier is lost, or if the sysop wants to return the user to the BBS system using function key F8. You should check this flag in all major loops in the door program. ck_FORCEOFFHOOK ------------------------------------------------------------------- Defined As: short ck_FORCEOFFHOOK Description: This variable should be set to TRUE or FALSE in the CKIT.H file. If this variable is TRUE, the modem will be placed OFF-HOOK if carrier is dropped in the door before returning to the system. If FORCEOFFHOOK is false, the door will not take the modem off-hook. See CKIT.H ck_USERFILE ------------------------------------------------------------------- Defined As: short ck_USERSFILE Description: This variable should be set to TRUE or FALSE in the CKIT.H file. If this variable is TRUE, C-KIT will open the Users file and those variables will be available. If not, only the PCBOARD.SYS file will be opened and the user information will not be available. See CKIT.H. ck_option ------------------------------------------------------------------ Defined As: unsigned char ck_option; Description: This variable is set to indicate how the user was logged off the system.

Some are used for customization of your door program and MUST be defined. Others using are meant to be read only variables available globally. Some are are used in conjuction with high level functions as noted. char progname[] pcboard.sys door.sys wildcat! generic ------------------------------------------------------------------ Defined as: char progname[21]; Description: Set this to your Door program name. It will be display on the status line on the sysop screen. MAXIMUM length is 20 characters! Do not exceed this! NOTE: THIS IS NOT AN OPTION. You must define progname[] even if you do not plan on using it. ck_cmdline[] pcboard.sys door.sys wildcat! generic ------------------------------------------------------------------ Defined as: BYTE ck_cmdline[128] Description: This is used by get_cmdline(), to read the user keyboard input to. Please see the CKITDEMO.C for usage. See Also: ck_get_cmdline(); ck_par[] pcboard.sys door.sys wildcat! generic ------------------------------------------------------------------ Defined as: char ck_par[128]; Description: This is used by get_nextpar(), to parse stacked commands to.

(F1-F10, PgDn, PgUp etc). The remote user must be in some type of terminal program that will allow passing the keycodes. Qmodem in "DOORWAY" mode is one example. Please see ck_input(), ck_get_cmdline() and ckitdemo.c for examples. See Also: ck_get_cmdline(); ck_key_source pcboard.sys door.sys wildcat! generic ------------------------------------------------------------------ Defined as: short ck_key_source; Description: This variable will a 1 if the input from get_cmdline() came from the LOCAL console or a 2 if it came from a REMOTE console. See Also: ck_get_cmdline(), ck_input() System Global Variables ck_linenum pcboard.sys door.sys wildcat! generic ------------------------------------------------------------------ Defined as: short ck_linenum; Description: This variable be will incremented each time a call to newline() is made. See Also: ck_page_length, ck_newline() ck_logoff_msgs pcboard.sys door.sys wildcat! generic ------------------------------------------------------------------ Defined as: char **ck_logoff_msgs; Description: This is pointer to an array of pointers that will be printed at the time the door is closed. The array of pointers has a length of 6 elements. Which message is printed depends on the value of ck_option. The code looks for an array of pointers to the exit messages and uses the ck_option variable to pick which one to print. This pointer to the array of pointers allows you to define your own array of pointers to the 6 exit messages. This allows the messages to be of any length and which message printed will be based on the value of ck_option (0-5) respectfully. See also the variable ck_option. They must be in this order. Example to create your own log off messages of ANY size. In your source code: char option0[] = "New Returning to system msg, any size\n"; char option1[] = "New CARRIER DROPPED! msg, any size\n"; char option2[] = "New Keyboard Timeout! msg, any size\n"; char option3[] = "New Sysop requests return to BBS msg, any size\n"; char option4[] = "New System time has expired! msg, any size\n"; char option5[] = "New Thanks for calling! msg, any size"; static char *logoffs[6] = { /* create array of ptrs */ option0, option1, option2, option3, option4, option5, }; ck_logoff_msgs = &logoffs[0]; /* Set C-KIT's pointer to custom messages*/ System Global Variables ck_logoff_msgs <cont.> ------------------------------------------------------------------ You do NOT have to define your own log off messages. C-KIT has it's own internal defaults. If you want to change just one individual log off message and leave the rest alone, then you can use the pointer that is initially contained in **ck_logoff_msgs and index to the one you want to change. Doing this will limit the size to the max. indicated for that message. The limits on changing individual logoff internal library messages are: MAX SIZE! ======== option0[40] /* internal "returning to board" msg */ option1[16] /* internal "NO CARRIER!!" msg */ option2[40] /* internal "keyboard timeout" msg */ option3[48] /* internal "sysop request" msg */ option4[36] /* internal "time expired" msg */ option5[40] /* internal "goodbye" msg */ To change only one internal logoff library message, use the pointer that is originally contained in **ck_logoff_msgs. Indexing from it, you can use strcpy() to change it. EXAMPLE: To change only the "returning to board" msg. IN YOUR source code: char exit_msg[40] = "Returning to system\n"; /* Max 40 allocated in lib */ strcpy(*(ck_logoff_msgs), exit_msg); /* Using the orignal pointer, copy new string */ To change only the "goodbye" msg. IN YOUR source code: char logoff_msg[40] = "Thanks for calling\n"; /* Max 40 allocated in lib */ strcpy(*(ck_logoff_msgs + 5), logoff_msg); /* Use the original pointer */ Again, you can provide your own array of pointers and change all the messages to any size desired. Look at the ckitdemo.c, ckitdemo.h. System Global Variables ck_gen_msgs pcboard.sys door.sys wildcat! generic ------------------------------------------------------------------ defined as: char **ck_gen_msgs; Description: This is pointer to an array of pointers that are C-KIT's internal messages. The array of pointers has a length of 12 elements. The code looks for an array of pointers to index which message to print. This pointer to the general array of pointers allows you to define your own array of pointers to the 12 internal messages. The messages can be of any length and which message printed will be based their position in the array. The ordering of the array is - 0 - Screen display on message 1 - Event pending warning, time adjusted 2 - Press enter to continue message, used with FORCE_ENTER. 3 - Sysop chat active msg 4 - Sysop chat end msg 5 - Sysop exited to DOS msg 6 - Sysop back from DOS msg 7 - (Enter=none)? msg used in get_defn() and get_defen() 8 - (Enter=yes) msg used in get_defyn() 9 - (Enter=no) msg used in get_defyn() 10 - (Enter) or (Y)es, (N)o, (NS)nonstop? msg used in no_more & display_file 11 - More: - msg used in no_more and display_file ck_gen_msgs = &ckitmsgs[0]; /* Set pointer to custom message ptrs */ You do NOT have to define these messages. C-KIT has it's own internal defaults. If you want to change just one individual message and leave the rest alone, then you can use the pointer that is initially contained in **ck_gen_msgs and index to the one you want to change. Doing this will limit the size to the max. indicated for that message. The limits on changing individual general internal library messages are: MAX SIZE! ======== msg0[18] /* internal "Screen on" msg */ msg1[44] /* internal "Event pending" msg */ msg2[28] /* internal "Enter to cont." msg */ msg3[48] /* internal "Sysop Chat" msg */ msg4[18] /* internal "Chat end" msg */ msg5[42] /* internal "Exit to DOS" msg */ msg6[40] /* internal "Return from DOS" msg */ msg7[14] /* internal "prompt1" msg */ msg8[12] /* internal "prompt2" msg */ msg9[10] /* internal "prompt3" msg */ msg10[38] /* internal "prompt4" msg */ msg11[6] /* internal "More: " msg */ System Global Variables ck_gen_msgs <cont.> ------------------------------------------------------------------ To change only one internal general library message, use the pointer that is originally contained in **ck_gen_msgs. Indexing from it, you can use strcpy() to change it. EXAMPLE: To change only the "Screen display on" msg. IN YOUR source code: char display_msg[18] = "<Screen ON>"; /* Max 18 allocated in lib */ strcpy(*(ck_gen_msgs), display_msg); /* Using the orignal pointer, copy new string */ To change only the "Exited to DOS" msg. IN YOUR source code: char dos_ret_msg[42] = "Sysop exited to DOS\n"; /* Max 42 allocated in lib */ strcpy(*(ck_gen_msgs + 6), dos_ret_msg); /* Use the original pointer */ Again, you can provide your own array of pointers and change all the messages to any size desired. Look at the ckitdemo.c, ckitdemo.h. ck_system_time_HHMMSS[] pcboard.sys door.sys wildcat! generic ------------------------------------------------------------------ Defined as: char ck_system_time_HHMMSS[9]; Description: This string will contain the current system time in the form HH:MM:SS and is available for general use. ck_todays_date_MMDDYY[] pcboard.sys door.sys wildcat! generic ------------------------------------------------------------------ Defined as: char ck_todays_date_MMDDYY[9]; Description: This string will contain the current system date in the form MM:DD:YY and is available for general use. ck_error_msg11[] pcboard.sys door.sys wildcat! generic ------------------------------------------------------------------ Defined as: char ck_error_msg11[40]; Description: Error message used by display_file. If you do not define this, C-KIT will default to it's standard error message. MAX. 40 chars. (not including NULL). ck_chatmode pcboard.sys door.sys wildcat! generic ------------------------------------------------------------------ Defined as: short ck_chatmode; Description: This variable will a 1 (TRUE) if chat mode or a sysop drop to DOS has been active. Use this to re-fresh your screen if needed. It is YOUR responsiblity to de-assert the variable after you have used it. (set to FALSE) System Global Variables ck_DOTS ------------------------------------------------------------------ Defined as: BYTE ck_DOTS; Description: This variable when set to a non-zero value will echo that value (character) to the to the remote/ local screens when using input() or get_cmdline(). For instance, setting ck_DOTS to a '.' will cause dots to be echoed to the screen. Handy for using with passwords etc. Resetting back to a NULL will resume normal operations. Standard Data Types Standard Data Types CKIT.H defines a number of useful data types. BYTE ------------------------------------------------------------------- Defined As: typedef unsigned char BYTE; Description: The BYTE data type is useful in serial communications since it provides an easier and more logical way of handling 8 bit data from UART's used in serial communications. Functions Functions The C-KIT Library contains a variety of functions. They are described as follows: Summary: Presents an exact syntactic model for each of the C-KIT Library functions. Description: Describes a function's purpose and how it is used in an application program. Return Value: Explains any of the possible return values for a C-KIT Library function. See Also: Lists any similar or related C-KIT Library function. Example: Illustrates how a C-KIT Library function could actually be used in an application program. Most function listed in the examples will be simply listed as function(). This may not indicate how they are called. To see how they are prototyped and called go to that function's page. I.E. If open_door is used in an example (other than it's own example) it may be simply refered to as open_door(). In reality open_door is really open_door(char * ...); The library functions are classified as 3 different types. High level, intermediate and low level. Normally a door would not need to make use of any of the functions except the high level functions. These handle and watch all the system timeouts, carrier detects, keyboard timeouts etc. If you need more control, there are other functions available. I will warn you. The lower level function you use, the less it will check for you automatically. Do not use these unless you have to. Functions ck_open_door ------------------------------------------------------------------- Summary: #include "ckit.h" short ck_open_door(); Description: The open door function initializes vectors, reads bbs system information. THIS MUST BE CALLED FIRST! The first pointer should be be the path/name to the system file. The second pointer should be the path/name to the users file, if you designated USERSFILE=TRUE. open_door() will also accept a pointer to a data structure if ck_NOSYSTEM is TRUE. (for pcboard systems only). As long as you have defined USERSFILE = FALSE, C-KIT will not attempt to use the second pointer. Which ever you specify, the PORT:AAAA:X (if used) must be the last parameter passed to open_door();. Close_door MUST be called before exiting program after a call to open_door. See the CKITDEMO.C for more examples. Return Value: Will return NULL is successful, otherwise it will return an error code listed below. See Also: ck_close_door Example: This example assumes the path\filenames passed on the command line. i.e program_name path\filename path\filename port #include "ckit.h" short result; main(int argc, char **argv) { if (argc > 0) { if(!ck_open_door(argv[1], argv[2], argv[3])); <--- NOTE: display_info(); argv[2] and your_main_program(); argv[3] are } else { optional. printf("Error opening door!"); see below. } ck_close_door(); exit(0); } } open_door() returns these codes: 0 ;Successful 1 ;Unable to open BBS system file (pcboard.sys,door.sys etc) 2 ;Problem reading BBS system file 3 ;Unrecognized BBS file type 4 ;Unable to open pcboard USERS file 5 ;Invalid User record or problem seeking to user record 6 ;Problem reading USER record 7 ;PORT command syntax error 8 ;Fossil driver specified but no Fossil driver installed 9 ;Memory allocation problem Functions ck_open_door <cont.> ------------------------------------------------------------------- NOTE: Both PORT and USERSFILE are optional. If a user of your door needed to specify a non-standard port address and IRQ, then the syntax is PORT:AAAA:X where AAAA is the base address and X is the IRQ. It doesn't matter whether PORT:AAAA:X is the second or third parameter (depending on if you were opening the user file) passed to open_door() as long as it is the LAST parameter passed. Note also it does not matter which order on the cmd line the arguments are listed. The only thing that matters is which order they are passed to the open_door() function itself. You could also have the system path as part of a config file for your door. Then you would read your config file and pass the path read from it to open_door() as a string ptr. PORT is optional, and C-KIT will default to standard addresses and irq's if PORT is not used based on the port number read from the BBS file. C-KIT will assume COM1 = 03F8 IRQ 4, COM2 = 02E8 IRQ3, COM3 = 03E8 IRQ4 and COM4 = 02E8 IRQ 3. If the sysop had a different non-standard port address and irq, he could then use the PORT cmd to change the defaults. For this reason, you should include the usage of PORT in your door program and documenation. Below is some examples of how your program would/could be called up and how the open_door() function would be called. Notice PORT is always the second or third (last) argument to be passed if a user of your door program wanted to use it. C-KIT will also support the use of FOSSIL drivers. The syntax for a FOSSIL driver is: PORT:F:P. The 'F' tells C-KIT to use a Fossil driver for it's communications. The 'P' following it tells it which port to use for the Fossil. Example - PORT:F:1, tells C-KIT to use a fossil driver for port 1. YOU AS A DOOR AUTHOR SHOULD ALSO INCLUDE THIS INFORMATION IN YOUR DOOR DOCUMENTATION FILES AND INCLUDE IT IN YOUR CALL TO OPEN_DOOR(). open_door() works like this. It will expect the first pointer to be a string pointer to the BBS system file, always. Next, it checks to see if USERSFILE = TRUE. If so, it will expect the second pointer to be a string pointer to a PCBoard users file. If USERSFILE is FALSE it will not look for a users file. Either case, open_door() will search the stack frame pointers for the word "PORT" for the 2nd and 3rd string pointers passed. If it finds it, it will utilize it. If not, it will use the default port addresses/irq's defined above for the COM port read from the system file. For this reason, open_door() will work whether there is actually a port command being passed or not. You as the door author should provide the users of your door the ability to pass the port command if they are using NON-STANDARD ports. Functions ck_open_door (cont.) ------------------------------------------------------------------- EXAMPLES: Assume door.cfg below is a config file that your door programs reads. This all depends on how or what is desired for your door program. You would need to document in your door documentation what order the cmd line should be for your door program, OR read your config file and pass the system name and path to open_door(). You should also include info about the PORT:AAAA:X in your docs. Here is a short example of reading a config file and passing the system name and path. (Assuming the 1st line in the config file has the system path\name) main(int argc, char **argv) { short handle, bytes_read; char bbssyspath[81]; handle = open(argv[1], O_RDONLY); /* Open config file */ bytes_read = read(handle, bbssyspath, 80); /* Read system path\name */ bbssyspath[bytes_read - 1] = '\0'; /* Null terminate */ close(handle); /* Close config file */ ck_open_door(bbssyspath, argv[2]); /* include arg2 for the PORT cmd */ ck_close_door(); } Your program's cmd line for the above could be any one of the following: doorprgm config.cfg ;Using standard ports doorprgm config.cfg PORT:03E8:5 ;Using non-standard port doorprgm config.cfg PORT:F:1 ;Using a fossil driver on port 1 You may not need or want a config file for your door program so you could just simply have the sysop pass the system infomation on the command line. If this is the case, your program's cmd line could be any of the following: doorprgm c:\wc\callinfo.bbs ;Using standard ports doorprgm c:\wc\callinfo.bbs PORT:03F8:5 ;Using non-standard port doorprgm c:\wc\callinfo.bbs PORT:F:1 ;Using a fossil driver on port 1 Again, you as the door author would explain in your documentation how the sysop would set your door program up depending on how you decide to handle reading the system files. Just be sure and include information about the PORT:AAAA:X and PORT:F:P commands as well. Functions ck_open_door (cont.) ------------------------------------------------------------------- HIGHLY RECOMMEDED!: You should include in your door source code C's atexit() function. Then have it call a function that will test if door_open() has been called or if close_door() has already been called. Then if your program has a runtime error, you will call close_door() so all interrupts vectors can be restored and prevent a system crash. Take a look at ckitdemo.c. EXAMPLE: short OPENED; /* Flag to know if open_door has been called */ short CLOSED; /* Flag to know if close_door has beeb called */ void shut_down(void); /* Shuts door down if normal or error occurs. */ main(int argc, char **argv) { open_door(argv[1], argv[2]); OPENED = TRUE; /* Door has been opened */ atexit(shut_down); . . . } /**************************************************************************** * Close door, reset vectors etc. * * Need in case of a run time error occurs in door * * and to check if a call to close_door needs to be made. * ****************************************************************************/ void shut_down(void) { if(OPENED && !CLOSED) { close_door(); CLOSED = TRUE; } } Functions ck_open_door (cont.) ------------------------------------------------------------------- Another way open_door() can be used is thru the use of a data structure defined as: typedef struct ckitgeneric { char port[6]; /* COM:? */ short min_left; /* minutes left */ }; This allows you to support BBS programs in your door program that are not supported directly by Ckit. To do this, you would read the BBS system file yourself. Obtain the necassary information for the data structure, set ck_NOSYSTEM = TRUE, then call open_door(). Below is a short example of reading a WWIV file. (WWIV is not directly supported by CKIT). typedef struct ckitgeneric { char port[6]; /* COM:x (COM0: is local) */ short min_left; /* minutes left */ }; struct ckitgeneric ck_gen; /* You can name this whatever you want */ char *ptr; if(WWIV) { open_file(bbs_system_file); read_file(bbs_system_file); setup_ck_gen(); /* set up data structure */ ck_NOSYSTEM = TRUE; ptr = &bbs_system_file); } else { ptr = &bbs_system_file; ck_NOSYSTEM = FALSE; } open_door(ptr, argv[2]); (2nd arg is for passing the PORT:AAAA:X cmd) Take a look at the ckitdemo.c file for a complete example. Functions ck_close_door high level ------------------------------------------------------------------- Summary: #include "ckit.h" void ck_close_door(void); Description: The close door function resets vectors, closes files opened and prints the log off message. THIS MUST BE CALLED LAST and ONLY after open_door(). Close_door MUST be called before exiting program after a call has been made to open_door. Not doing so will certainly cause a system lock up. See above for using C's atexit() function. Version 2.0 and above, close_door will check if open_door has been called or if close_door() has already been called to help further prevent any system hangups. Return Value: No value is returned. See Also: ck_open_door. Example: #include "ckit.h" main(int argc, char **argv) { if (argc > 0) { ck_open_door("d:\wc\callinfo.bbs"); . . . . your door program . . ck_close_door(); }; }; Functions ck_update_user PCBOARD 14.5 only high level ------------------------------------------------------------------- Summary: #include "ckit.h" void ck_update_user(); Description: The update user will accept a POINTER to the user structure member to update. See the user structure above. This function will only work for PCBoard 14.5 and USERSFILE must be set TRUE. C-KIT will update the user file when the door is closed. If you do not want C-KIT to update the user record after a change has been made set USERSFILE = FALSE before calling close_door(); If you use this function you should set the compiler to use WORD alignment for C-kit v.2.01 and below. NOTE: IN VERSION 2.08 AND ABOVE, YOU NEED TO USE BYTE ALIGNMENT! Return Value: No value is returned. See Also: ck_user structure Example: Change user security and comment1 field. MOTICE THE & BELOW!. You MUST pass the address of the member to update in the user structure. #include "ckit.h" main(int argc, char **argv) { USERSFILE = TRUE; static char new_comment[] = "ckit_user"; if (argc > 1) { ck_open_door(argv[1], argv[2]); (pass system file and PORT cmd) . . . ck_usersecurity = 50; ck_update_user(&ck_usersecurity); strcpy(ck_usercomment1, new_comment); ck_update_user(&ck_usercomment1); . . . ck_close_door(); }; }; Functions ck_s_puts high level ------------------------------------------------------------------- Summary: #include "ckit.h" void ck_s_puts(char *); Description: The s_puts function displays a single NULL termintated (C string) to the local and remote console. It expects a pointer to the string of type BYTE or char to be displayed. It will not handle ANSI. See ck_s_putstd() for ANSI and other usage. Return Value: No value is returned. See Also: s_printf, ck_s_putv, ck_s_putc, ck_s_putsn Example: #include "ckit.h" static BYTE string[] = "This is a test"; main(int argc, char **argv) { if (argc > 1) { ck_open_door(argv[1]); /* pass system file(s) */ . . . ck_s_puts(string); ck_s_puts("This is also a test"); . . . ck_close_door(); }; }; Functions ck_s_putstd high level ------------------------------------------------------------------- Summary: #include "ckit.h" void ck_s_putstd(char *); Description: The s_putstd function displays a single NULL termintated (C string) to the local and remote console. It expects a pointer to the string of type BYTE or char to be displayed. This function is identical to s_puts except it uses std output. This function should be used when ANSI code, or CTRL chars are needed to be sent to the local and remote consoles. Return Value: No value is returned. See Also: s_printf, ck_s_putv, ck_s_putc, ck_s_putsn Example: Use s_putstd() to change background/foreground colors #include "ckit.h" #define cyanblue 0 #define yellowbrown 1 #define redgreen 2 #define redcyan 3 #define cyanred 4 #define cyanmagenta 5 #define bluegrey 6 static char *ansi_color[8] = { "\33[0;1;36;44mCyan on Blue\33[40m" "\33[44m\33[33;43mYellow on Brown\33[40m" "\33[43m\33[0;31;42mRed on Green\33[40m" "\33[42m\33[46mRed on Cyan\33[40m" "\33[46m\33[1;36;41mCyan on Red\33[40m" "\33[41m\33[45mCyan on Magenta\33[40m" "\33[45m\33[0;34;47mBlue on Grey\33[0m" }; main(int argc, char **argv) { if (argc > 0) { ck_open_door(argv[1]); /* pass system file(s) */ . . . ck_s_putstd(ansi_color[cyanblue]); ck_s_putstd(ansi_color[yellowbrown]); ck_s_putstd(ansi_color[redgreen]); ck_s_putstd(ansi_color[redcyan]); ck_s_putstd(ansi_color[cyanred]); ck_s_putstd(ansi_color[cyanmagenta]); ck_s_putstd(ansi_color[bluegrey]); . . . ck_close_door(); }; }; Functions ck_s_putv high level ------------------------------------------------------------------- Summary: #include "ckit.h" void ck_s_putv(); Description: The s_putv function displays a single NULL terminated (C string) to the local and remote console. It expects a variable argument of pointer(s) to the string(s) of type BYTE or char to be displayed. The list of pointers MUST end with a NULL pointer!. Not doing so will most likely either cause garbage to printed or even a hang-up. Return Value: No value is returned. See Also: s_printf, ck_s_puts, ck_s_putc, ck_s_putsn Example: This example prints 2 strings with the pointer list terminated with a NULL pointer. #include "ckit.h" static BYTE string[] = "This is a test"; main(int argc, char **argv) { if (argc > 1) { ck_open_door(argv[1]); /* pass system file(s) */ . . . static BYTE string[] = "This is a test"; ck_s_putv(string, "This is also a test", NULL); . . . ck_close_door(); }; }; NOTE: an alternative to using s_putv would be to include the function s_printf() below in your source code. You could use this function the same as you would printf(); This function has already been protyped in CKIT.H Functions s_printf high level ------------------------------------------------------------------- Summary: #include "ckit.h" void s_printf(char *,...); Description: The s_printf function is used to format an output to be sent to the local and remote console. It is exactly the same as the cprintf() function in C. To use it, you must include the source code listed below in your door program since s_printf() is NOT an actual part of the C-KIT librarys.

Default is 2 minutes beep and 5 minute timeout. This allows the door author to set the keyboard timer. The time has a resolution in minutes, with a minimum of 1 minute and a maximum of 255. The routine expects two numbers. The first number is the BEEP time. This sets how many minutes should pass before the keyboard timer gives a warning beep. It will continue to beep afterwards at one minute intervals. The second number is the actual keyboard timeout value. It should normally be set to some number higher than the BEEP time. NOTE: Each call to ck_set_kybd_time() will reset the current keyboard timer to zero. Example: Set the BEEP time to 2 minutes and timeout to 6 minutes. #include "ckit.h" main(int argc, char **argv) { if (argc > 1) { ck_open_door(argv[1]); . . . ck_set_kybd_time(2, 6); . . . ck_close_door(); }; }; Functions NOTE: ALL the low level functions below are not normally needed and are handled automatically by C-KIT in a higher level function.

This applies if you are planning to use the ck_users structure AND/OR the ck_update_user() function. The default on BORLAND is BYTE alignment. This will not work correctly for these two items. If you are not using either the ck_users file structure or ck_update_user(); function, then you don't have to use WORD alignment, BYTE alignment will work OK. See the file TCREAD.ME in the CKIT_TC.ZIP file. In addition, TURBO C++/BC++ users should also select standard stack frame alignment. Make a dir to work from. Copy the CKITDEMO.C, CKITDEMO.H, CKIT.H, the CKIT_T?.LIB's, and the TCPPCKIT.PRJ or CKITS.PRJ into the same dir. Bring up the TURBO C IDE and select the proper project file and you can test the CKITDEMO.C. Have it create an .exe file. This should get you started. You can take it from here... This package can be freely distributed so long as it is not modified or sold for profit. If you find that this program is valuable, you can send me a donation for what you think it is worth.

ACKNOWLEDGEMENTS -------------------- I would like to give special thanks to my Co-sysop, Dean McGuire, who has patiently tested the door routines and for help preparing the documentation. GENERIC.SYS -------------------------- For maximum compatibility, C-KIT will also read a file called GENERIC.SYS. This file can be created by the sysop desiring to run the door and allow C-KIT to operate. This would allow your door to operate on ANY BBS system. (see compatibilty issues below). The GENERIC.SYS file is a standard ASCII file and contains 3 lines, each followed by a carriage return, line feed. The format is: line 1 - The BBS operator's name. line 2 - The COM port in use. line 3 - Time allowed in door. When C-KIT finds a GENERIC.SYS, it will ask the user for his/her first and last names before opening the door. After the user inputs their name, the door will continue to load and run. Below is an example GENERIC.SYS file with a sysop name of Rickie, using Com port 1, and allowing 50 minutes in the door. Rickie COM1: 50 Each line is followed by a C/R, L/F and the com port follows the same format as the standard door.sys. COM0: = Local Mode (same as door.sys) See the compatibilty issues below for more information. NOTE: You should include this information in your door documentation also. COMPATIBILITY ISSUES -------------------------- Although C-KIT makes a lot information available to the user, the author has to decide on what particular information his or her door will require. Here are some general guidelines that may help. Decide on exactly what information your door will need to operate. Keeping this to a minimum increases your chances of maintaining compatibility thruout the different BBS's systems and versions thereof which C-KIT supports. For example, let's assume you are designing a standard BBS game. C-KIT handles all the detailed information such as time left, carrier detect etc. All you would really need is some basic information. Perhaps just the user's name and sysop name. By keeping this type of information to the minimum, your door would work regardless of whether the sysop running your door used pcboard.sys, door.sys, callinfo.bbs or GENERIC.SYS on the command line..i.e, game.exe c:\pcb\pcboard.sys OR game.exe c:\pcb\door.sys OR game.exe c:\wc\callinfo.bbs, OR game.exe c:\GENERIC.SYS OR game.exe c:\rbbs\DORINFOx.DEF;, ANY of these would work. (If the sysop was running PCBoard 12.0, he would only be able to use pcboard.sys. In this case, C-KIT would not only take care of deciding if it was a pcboard.sys file, door.sys file, WILDCAT! callinfo.bbs or DORINFOx.DEF, but also if it *is* a pcboard.sys file, whether it is a PCBoard 12.0 sys file or later, and then would read it properly!). This would make your door compatible with the full spectrum of PCBoard 12.0-14.5, WILDCAT!, GAP, SPITFIRE 3.0, other systems using the standard door.sys file, RBBS and others using DORINFO1.DEF and ANY BBS using GENERIC.SYS with minimum effort on the part of the sysop running your door. Once you've written this fantastic new door, if it's a snap for a Sysop to install it, this might make him a bit more inclined to register it, right? Another senario would be if your door needs somewhat more than the basic information. I would recommend using the variables available in door.sys and WILDCAT! info file in this case. This would give you the broadest coverage for your door. If you will notice in the variables descriptions in this manual, there is a compatibility list to the right of each variable. This tells you which and what type of information is available to you depending on whether your door found a door.sys, pcboard.sys (and which version of PCBoard), WILDCAT! info file and DORINFOx.DEF file. Below is a summary and quick guide to each pcboard.sys version, door.sys, WILDCAT!, DORINFOx.DEF info file and which information variables are available with each. If you need EVEN more information, then you can tell C-KIT to open the users file and read information. Doing so will limit your door to PCBoard systems only. C-KIT will NOT record any information to the user's file unless a call to update_user has been made. It will also not record anything to sysop record.

When C-KIT reads a pcboard.sys file, it will set the PCB variable TRUE. If the pcboard.sys file it read was a 12.0 file, it will set the PCB12 variable true. If C-KIT finds a WILDCAT system, it will set the variable WILDCAT true. This may be useful in making adjustments to your program depending on which system file was read (PCB, DOOR.SYS, PCB12, WILDCAT) and/or if a sysop was running PCBoard 12.0 and you normally expected door.sys or wildcat info file. If C-KIT finds a door.sys file, GAP will be set true. Also, see the users file information earlier in the doc file. Some of the users structure information is available even if you are just using door.sys. If you do tell C-KIT to open the users file, all the users file information above will be available, if C-KIT finds a version 14.x pcboard.sys. If it finds a PCBoard 12.0 pcboard.sys file, some, but not all, of the users structure information will be available. Each member of the users structure is marked to indicate what is available and what is not depending on the things just mentioned.

Signed: _________________________________________ Date: _________ RELEASE HISTORY ------------------- see history file SOME COMMON PROBLEMS/QUESTIONS ------------------------------ Q. How can a test my door in "local" mode? A. There is a door.sys file included with the C-KIT libraries. The first line in the door.sys file is COM0:. With accordance to doorsys specs., this specifies "local" mode. Use this file for testing your doors. You can modify the door.sys file to also use a com port for online testing. See the doorsys.txt for more information. You could also make up a GENERIC.SYS file and use COM0: as the port. See the section on GENERIC.SYS. Q. When linking my code with the library I get a linker error - Unresolved external _progname in CKIT3.ASM. A. C-KIT will look for a C string array called progname[21];. This the name of your door program and will appear at the bottom of the local line. This is not an option. You must declare some kind of name for C-KIT to use even if it just a space char if you don't want your progname at the bottom. See the CKIDEMO.H file for example and the variable progname[] in the doc file. Q. When linking your ckitdemo program, I get an error - Unresolved external _random in ckitdemo.c A. The Ckitdemo.c door was written to be compiled with either Microsoft C or Turbo C. As such, there are compiler directives in the CKITDEMO.C file that will take appropriate action depending on the compiler. Therefore, when compiling the CKITDEMO.C program, you must have the statement -DCOMPILER=MICROSOFT or -DCOMPILER=TURBOC on the command line. This is needed only when compiling the CKITDEMO.C program. It is NOT needed when you are compiling your own door program. Q. Do I have to include the -DCOMPILER-MICROSOFT or -DCOMPILER=TURBOC on the command line every time I compile my door program? A. No, this was only needed for the CKITDEMO.C source code. You can also modify the ckitdemo.c and ckitdemo.h file and take the compiler directives out if you like. Then you would not have to use it when compiling the ckitdemo.c. (Just make sure you take the right ones out for whichever compiler you are using). Matter fact, the way the defaults are defined in CKITDEMO.C, and CKITDEMO.H you don't need to have the -DCOMPILER=TURBOC when using TURBO C to compile the ckitdemo.c file or using Turbo C's IDE. Q. My F4, F3, F7, ALT X, ALT N keys do not do have any effect when returning to the BBS. A. These keys are valid only on doors or sysops using the pcboard.sys file. When the code finds a door.sys or Wildcat! info files, it will make no attempt to update a pcboard.sys file. F5 shell to DOS, F8 return to BBS, F9 screen on/off will work with any system. Try and write your door so that the sysop can use pcboard.sys if he is a PCBoard sysop but will also run on other systems as well. Future updates will take into consideration other systems as permitted. See the compatibility chart above. Q. Why all the formfeeds in the documentation? A. This is so that people with access to a copier can print them out, run the printed sheets thru the copier and duplex (print on both sides) the sheets into a manual. If you do not want the form feeds, just do a global replacement with your favorite editor and get rid of them. Q. I thought C-KIT required that the users file path be listed also? A. NO. This was used for the CKITDEMO file only. C-KIT library does not care one way or another about the users file being open. CKITDEMO is also written to work with ANY system. Ckitdemo is a demostration of how a door can be written to accept any command line given and make adjustments accordingly. Ckitdemo will accept either: ckitdemo.exe c:\pcb\pcboard.sys c:\pcb\main\users ckitdemo.exe c:\pcb\door.sys ckitdemo.exe c:\wc\callinfo.bbs PORT:03e8:5 See the open_door() function for more information. Q. Will C-KIT work with any systems users file? A. NO. If you require information from the user file it must be be PCBoard 14.x or PCBoard 12.0. However, by doing so you will be limiting your door to the number of systems it can be ran on. I would not recommend using user file info unless your door is being written specifically for PCBoard. Other system files (pcboard.dat, msgs and other systems users file) will be included in the form of source code at a later date. This will allow you to link those with the existing C-KIT library functions. Q. What baud rates can C-KIT can handle? A. C-KIT can handle ANY baud rate from 50 baud to 230K baud. (these are the baud rates it has been used with). The highest baud any standard IBM compt. system can produce is 115K baud. The 230K baud was done on a modified IBM AT by changing the UART's xtal and using 16550A UARTs. Q. I'm using MSC 6.0 and when I compile my program I get a message "warning 'NULL' : macro redefinition"? A. This is not a problem. It is actually a carry over from MSC5.1. If you wish, you can remove the line #define NULL = 0 in the CKIT.H header file. MSC 6.0 redefined their NULL assignment in the stdlib.h file which causes this. You will not get the warning with MSC 5.1 or lower and TURBO C. Q. I'm using TURBOC and when I compile the small model demo program it works fine. But when I re-compile using medium model I get stack overflow fixup errors from the linker. A. TurboC does not delete and re-compile the CKITDEMO.C module. So when it attempts to link the older small model .obj file you created earlier with the medium library, you will get this error. When you switch memory models, you must delete the previous .obj file created using the small memory model. If this happened to be CKITDEMO.C, you would need to delete CKITDEMO.OBJ before changing memory models. Q. Some function keys are not trapped locally. A. Some keys are reserved on the local keyboard for sysop functions. Try to design your door without using the F3, F4, F5, F7, F8, F9 ALT-H, ALT-N, ALT-X. If you have to use these keys, they can be used by the remote keyboard but just be aware, you would not be able to use them on your local keyboard. Q. When linking my program, I get an error - Unresolved external _wait. A. This function was renamed to ck_wait in v1.7. You need to be using the CKIT.h header file. There was a conflict with one of Borland's library names. Q. Why does the user security level somtimes show on the status line and sometimes it doesn't? A. PCBoard.sys file does not provide that information. The security level will only show if you are using door.sys, callinfo.bbs (WILDCAT!) or you are using pcboard.sys and open the users file. The status line indicators for pagebell, printer and caller alarm will also not show up if you are using door.sys or callinfo.bbs but will if you are using any version of pcboard.sys from 12.0 up. Q. Will there be any kind of sign off message from C-KIT after the program is registered? A. After C-KIT is registered, the only message displayed when closing the door will be the one you defined using the *ck_logoff_msgs or the default "Returning to system ...".
