C Spot Run is a library of C and Assembly routines for C programmers. These routines supplement the standard libraries provided with compilers, and provide tools for specialized applications. All routines in this library are either in the public domain or are part of the user supported software world, as are the accompanying utilities and programming aids. Our goal is to provide low cost (free!) routines and utilities for C programmers. The use of pre-written routines greatly reduces the amount of tedious code writing in almost any situation, and we hope that our collection will prove to do so. 1.2. Why C Spot Run? What is probably the next question to cross your mind is simply, why? Good question, and I hope this is a good answer. Because. Because there are so many libraries similar to this one. Because they all cost money, and this one doesn't. Because as of yet there is no central distribution point for many of the C routines floating around in .C files everywhere. We feel that C Spot Run is filling a need, and we hope you agree with us. We would appreciate your taking some time to let us know what you think of the library and what directions you would like to see it take. Page 5 C Spot Run - Documentation 2. Obtaining and Copying C Spot Run 2.1. User Supported Software User supported software is software distributed at no cost other then a small media charge with the expectation that those who find it useful will send a donation to support the development. In most cases those who contribute become registered users and receive automatic updates, printed manuals, telephone support, and/or source code. 2.2. Ownership of C Spot Run Without a major essay on copyright laws, the routines and utilities in this package are the property of their respective authors, with the exception of those released to the Public Domain (PD). It is important to recognize the difference between Public Domain and user-supported software. (User-supported includes "ShareWare", "FreeWare" and several other names.) Unlike authors who totally give their software to the public domain, some authors distribute their code with a limited license, usually something to the effect that you are not to distribute modified versions or charge for the distribution. The routines and utilities in this library are either totally in the public domain, in which case their source code is present, or have been released to this library for distribution as described in Appendix C of this document. As to the library itself, and this documentation, they are property of Bob Pritchett, and released to the public under the limited license in section 2.4. 2.3. Contents of C Spot Run The very basic principle behind this library is user- supported software. In addition to monetary contributions, an even more valuable form is that of routines or utilities. Most of the routines and utilities in this library were written by two or three people, or are modifications of other routines in the public domain. We would like to build a sizable library of tools and helps for C programmers, and whether it is a new routine you wrote, or one that is already in the public domain world, your contribution of code and permission to let us use it would be appreciated. At present this library is a collection of routines and programming aids only. Since the release of the first version of the library, the response has been positive, and our interpretation of it is that the library should continue to focus on routines and programming aids, as opposed to creating a library of general C source code. 2.4. Distribution License for C Spot Run The C Spot Run library of routines and utilities may be freely duplicated and distributed under the following terms: Page 6 C Spot Run - Documentation o No fee may be charged other than reasonable expenses for media and reproduction, no more then eight dollars. o The library MAY NOT be distrbuted by any for-profit corporation, including, but not limited to, for-profit public domain software companies, without the express written permission of Bob Pritchett. o The routines, utilities, and documentation are not to be distributed in a modified form. o The routines and utilities are not to be used in commercial applications or business environments without the express written permission of the authors. o Credit must be given to authors whose routines are used in any distributed application, in both the code and program documentation, unless other arrangements are made directly with the author. Page 7 C Spot Run - Documentation 3. Using the C Spot Run Library 3.1. Using the Library with Your Compiler All utilities included in this library work with straight ASCII text files, unless otherwise specified, and those dealing with the syntax of the C language should work with all flavors of C that conform to the basic guidelines in K&R. The routines are distributed in several forms, usually either object code or source code, C or assembly. Specific information on each routine and it's compiler dependancies is available in the section entitled Compiler Specifics in each routine entry. As a general rule, object code and libraries are in the Microsoft/Lattice format. These libraries and object code modules can be linked to your program with LINK. If the source code is available simply check it for compiler differences (see the next section) and compile it with whatever compiler you use. 3.2. Modifying the Library Although many compilers use the same routines, they often are named differently, or use a different set of parameters. This section should be of assistance in modifying source to work with your, or someone else's, compiler. If you have some information that could be helpful in ocmpiler conversions, please contact us. 3.2.1. Problem Areas Some of the more common differences in compiler libraries are the naming conventions used. For instance, the routines to perform a DOS interrupt vary from intdos() to doint(), and have just as many differences in parameters. Some common differences are in string manipulation, hardware specific functions, and memory management. Here is some information that should be of help: 3.2.2. Helpful Suggestions Those with Microsoft C V3.0 should consult the header file V2TOV3.H for assistance, and Appendix D of the User's Guide, Converting from Previous Versions of the Compiler. Microsoft V3.0 uses unions declared in DOS.H as parameters for it's hardware/DOS functions unlike most other compilers which need the register variables etc. declared by the user. The register variables are stored in a union of type REGS, and are addressed using the union member x to access registers with x as a second character, or h to access the registers ending in h or l. Example: union REGS in; n = in.x.ax; y = in.h.bl; Microsoft's hardware interrupt is int86(int,&in,&out), cor- responding to sysint(int,&in,&out) used by many other compilers. Likewise intdos(&in,&out) corresponds to sysint(0x21,&in,&out). Page 8 C Spot Run - Documentation Lattice/Computer Innovation's movmem(source, destination, width) corresponds to Microsoft's movedata(destination, source, width). All of Microsoft's string manipulation functions are in the format strxxx() or strnxxx(). Example: strlwr(string) strcat(string1, string2) strncat(string1, string2, number). 3.3. Using the Utilities and Aids The use of utilities and programming aids should be clearly described on their description pages. All include files should be included at the beginning of sources that need them, and in addition to the description page most independant utilities will provide a short summary of their use when run with no command line parameters. Page 9 C Spot Run - Documentation 4. Format of Routine/Utility Descriptions 4.1. How to Use the Routine Description Pages The routine description pages are set up in such a manner that updates to the library will not require a totally new manual. Each routine has its own full page regardless of how small or large it is. The page is set up in a special order, with the name of the routine on the upper right of the page at the top for quick indexing, followed by a short summary of the necessary arguments and their data types. Next is a line containing the creation and last update dates, and then the author's name and whether the source is in C or Assembly. Following these is a list of the files in which the code is contained, a list of other required functions that may not be in every library, and then a paragraph description of the function. This is followed with a paragraph explaining any ties to one specific compiler, the return value, a list of related functions in the library, and a final example of how it might be used in a portion of code. It is recommended that you keep the complete manual in a three ring binder, and as you receive updates simply print out the enclosed page, and insert it in alphabetical order among the function description pages. (This manual may seem like a waste of paper, but this way it saves a lot in the long run.) 4.2. How to Use the Utility Description Pages The utility description pages are similar to the routine descriptions described above except for the layout of information. On the utility description pages the first item is, as with the routine descriptions, the utility name on the upper right hand corner. Next is a summary of the utility including the creation and last update dates, the author's name, the source language, and then a copy of the documentation, usually an exact duplicate of whatever documentation the author has sent. As mentioned, the method for updating these description pages is the same as above in section 4.1. Page 10 Date Manipulation Routines This library comes with a variety of routines that can be used to perform operations on and manipulate dates. When calling functions that require date elements the order of month, day, and year is used. The only exceptions to this ordering are the get_date() and set_date() functions, which work with the system's internal date. These routines require the arguments to be in the order of day, month, and year. All of the date manipulation routines are capable of accepting years in both the two and four digit formats. (IE. 1987 is evaluated in the same manner as is 87.) The number of days between two given dates can be calculated directly with the dt_diff() routine, or through subtraction using the serial numbers of each date, as calculated with date_sn(). At present the date routines do not take into account different calendar systems, and, with the exception of the year limited serial number routines, will assume all AD dates are in our current system. Directory Management Routines With the two basic file search routines ffirst() and fnext() any number of directories may be generated, and when combined with the windowing routines any application can have a convenient system for directory viewing and file selection. The possibilities are endless, thus only a limited number of directory viewing routines have been provided, but we trust that they will help you design and implement whatever file management you require. The following are some hints and suggestions: Finding and storing all the file names before displaying them has the benefit of allowing scrolling to take place forwards and back, but the disadvantage of a slight delay while reading in the information. If scrolling is needed, try saving the names as they are read and displayed, and keep pointers allowing you to scroll back, but not forward until the new file names are read. If it is neccessary to divide the file name and extension two obvious alternatives are presented. Either write a routine to go through the string containing the name, looking for the dot separater, and split the string into two parts, or use the sscanf() function to read the two fields into separate strings. Whatever you do with the provided directory routines, we'd appreciate a copy of your routine for curiosity's sake, and if possible, inclusion in a future version of the library. Graphics Routines This version of the library contains just a few simple graphics primitives that work with the Color Graphics Adapter. The routines provided perform simple graphics functions with no concern for the aspect ratio of the screen, relative coordinates, etc. All of the functions work with the exact coordinates given and mathamaticly calculated assuming an aspect ratio of one. (The IBM PC has a ratio of 1.2.) The purpose of these routines is to provide a very few basic routines for some form of graphics output. If you have a complete graphics system, or just one that's faster than that provided here, we would appreciate it if you would consider submitting a copy to the library. Input Routines The input routines are named in the following format: [w][f]inpt<type>[r][m][e][d](); [w] Window. If input is in a window, use the [w] prefix. NOTE: If the window pointer given is not to a valid window the result is undefined. [f] Field. Field input is input in a maximum length field. The color and fill character for the field is specified by fcolor() and fchar(). <type> Type. This mandatory part of the function name is the type of input being accepted. [r] Range. If there is a minimum and maximum entry this element is used in the name. [m] Mask. This element means that an input mask will be specified. [e] Editing. If the field supports full editing features, this element is used. [d] Default. If there is to be a default entry this element is used. All of these elements make for a large number of possible routines. However, only a few of these options are implemented, and users who have source code can use these functions as bases for new ones. For a list of which functions have been implemented with this version, please check the quick reference chart at the end of the manual. Printer Operation Routines The printer output routines included in this verson, 1.0, of the library are intended to provide only the basics for printer control. The routines provide for single character output, lputchar(), string output, lprint(), and formatted string output, lprintf(). These routines all call DOS function number 5 which means that with the DOS MODE command etc. the output can be redirected or reformatted. Many libraries include an extensive set of routines to set different attributes, fonts, and styles on printers. However, since these routines are usually dependant on one printer make, and generaly do little more then output two or three characters it was thought best to provide only the generic lputchar() function. If you would like to provide a set of printer specific or independant routines to perform these functions, please contact us. Real Time Timers The timer functions are designed to implement up to ten different elapsed time counters. The counters are numbered from zero to nine, each of which may be individually started, stopped, and read. The function init_tmr() must be called before any of the timers are used, although it needs to be called only once. These ten counters may prove especially useful in communications, timed input, or other 'real time' applications due to the fact that they work with the internal system clock and are not bus clock rate dependant. (The timer() routine, not a part of this collection, does report in clock ticks.) All of the timer functions, with the exception of init_tmr() and get_timer(), require a single integer argument with a value between zero and nine. Any other value will normalized into that range, which is the timer to use for that specific function call. The functions that return a time do so in tenths of seconds. (The maximum time any timer may track is approximately 1.8 hours.) These routines were contributed by Dave Perras who wrote them with a Datalight C compiler. The included source code should be easily portable to most MS-DOS C compilers. Window Function Library The C Spot Run window function library is a library of routines that perform background/foreground windowing. What this means is that any window that is overlapped by another window, when addressed for output, will be moved to the front of the 'stack' and become the active window. The window library also contains a large number of support routines to make movement of and output to windows as easy as possible. There are routines that make pop-up menus, center text, draw boxes, and do much more. Full color support is available, and for speed all of the cursor and output functions are in assembly. All windowing functions are in the file COUTPUT.OBJ, and source is not distributed. For ease of calling, in general you will find that all window functions are preceeded by a w in the function name, (wopen(), wclose(), etc.) and in most cases the first argument is the window pointer. For more information, consult the detailed function descriptions. I would like to thank Philip A. Mongelluzo whose Windows for C and Window BOSS packages were of invaluable use to me in the development of this package, not to mention the time he spent patiently answering my questions. border Summary: int border(color); int color; /* Color of Border */ Created: 12/28/85 Last Updated: 12/28/85 Author: Bob Pritchett Source (C/A): A Located in: BORDER.OBJ Requires: Nothing. Description: This function draws sets the screen border to the specified color using function 11 of the BIOS video interrupt. Works in text modes only. Compiler Specifics: Has Microsoft's assembly header, otherwise none. Return Value: Nothing. See Also: Example: border(4); /* Red Border */ box Summary: int box(x,y,x2,y2,type); int x; /* Upper Left Row */ int y; /* Upper Left Col */ int x2; /* Lower Right Row */ int y2; /* Lower Right Col */ int type; /* Style of Border */ Created: 08/ /85 Last Updated: 05/22/86 Author: Bob Pritchett Source (C/A): C Located in: BOX.OBJ Requires: gotoxy() putch() Description: The box function draws a graphic box using the upper left and lower right corner coordinates. The border style can be a combination of the double and single line characters of the IBM character set, or any other printable character used all the way around. The border is chosen with type. If type is equal to one, an all single line border is drawn. If it is two, a double horizontal line and single vertical line is used, if it is three it is an all double border, if it is four a single horizontal line and double vertical line are used. In the case of a five, three ASCII characters, + - |, are used. Any other value in type will cause the border to consist entirely of this character. Compiler Specifics: BOX.OBJ was compiled using MSC 3.0, but there are no compiler specifics involved other then putch(), the put character to console function. Return Value: Returns a one if successful, or a negative one if invalid coordinates are passed. See Also: cbox() Example: box(10,10,20,30,'*'); /* A box with a border of *'s */ cbcapt Summary: int cbcapt(flag); int *flag; /* Location of Integer Flag */ Created: 10/26/86 Last Updated: 10/26/86 Author: Source (C/A): A Located in: CBRKTRAP.OBJ Requires: Nothing. Description: This function allows the programmer to detect and handle a Control-C or Control-Break entered by the user. The function must be called with the location of a static integer which will be set positive when a Control-C or Control-Break is hit. The program may then choose to test and handle the flag, or ignore it totally, effectually disabling the break features. This function is based on routines in Advanced MS-DOS and The C Toolbox, by Ray Duncan and William Hunt. Compiler Specifics: None. Return Value: No return value. See Also: cbrest() Example: main() { static int flag = 0; timer(); cbcapt(&flag); while ( flag == 0 ) printf("Waiting for Ctrl-Break.\n"); printf("Control-Break detected after %ld clock ticks.\n" ,timer()); cbrest(); exit(0); } cbox Summary: int cbox(x,y,x2,y2,type); int x; /* Upper Left Row */ int y; /* Upper Left Col */ int x2; /* Lower Right Row */ int y2; /* Lower Right Col */ int type; /* Style of Border */ Created: 03/03/86 Last Updated: 03/03/86 Author: Bob Pritchett Source (C/A): C Located in: COUTPUT.OBJ Requires: putchci() gotoxy() Description: This function is functionaly the same as box() except that the box is drawn in the current color. It is primarily used as an internal routine in COUTPUT.OBJ. For independant use, use color() or wcolor() to set the color. Compiler Specifics: None. Return Value: Returns a one if successful, a negative one if invalid coordinates are passed. See Also: color() wcolor() box() Example: #include <color.h> /* Just for the colors... */ color(RED_F,WHT_B); /* Red on White */ cbox(5,5,20,60,1); /* A box with a single line border */ cbrest Summary: int cbrest(); Created: 10/26/86 Last Updated: 10/26/86 Author: Source (C/A): A Located in: CBRKTRAP.OBJ Requires: Nothing. Description: This function disables the Control-C and Control-Break trapping turned on by cbcapt(). While it is not always neccessary to call this function before exiting a program, it is a good practice. Compiler Specifics: None. Return Value: No return value. See Also: cbcapt() Example: main() { static int flag = 0; timer(); cbcapt(&flag); while ( flag == 0 ) printf("Waiting for Ctrl-Break.\n"); printf("Control-Break detected after %ld clock ticks.\n" ,timer()); cbrest(); exit(0); } ccenter Summary: int ccenter(row,string,color); int row; /* Row to Center String on */ char *string; /* String to Center on Screen */ int color; /* Color to Print String in */ Created: 12/28/85 Last Updated: 12/28/85 Author: Bob Pritchett Source (C/A): C Located in: CCENTER.C CENTER.OBJ Requires: gotoxy() ccputs() Description: This routine is functionaly the same as center() only that the line is displayed in the color specified. Compiler Specifics: CCENTER.OBJ was compiled with MSC 3.0, but there are no other compiler specifics involved. Return Value: Nothing is returned and there are no validity checks. Giving a string longer then 80 characters, or a line number less then zero or greater then 24 will produce an unknown result on screen, while it should return cleanly. See Also: center() putat() cputat() Example: #include <color.h> char *string; scanf("%s",string); ccenter(0,"This line is centered in color.",RED_F); ccenter(2,"This one is in magenta on black, as opposed to red." ,MAG_F); ccenter(3,"And yet another line, this time in green.",GRN_F); ccenter(5,string,WHT_F+BLU_B); ccls Summary: #include <color.h> /* For color definitions only... */ int ccls(color); int color; /* Color of Screen */ Created: 12/28/85 Last Updated: 12/28/85 Author: Bob Pritchett Source (C/A): A Located in: CCLS.OBJ Requires: Nothing. Description: This function clears the screen and sets all the attributes to the given color. The cursor is sent to the home position. Compiler Specifics: Has Microsoft's assembly header, otherwise none. Return Value: Nothing. See Also: cls() Example: #include <color.h> ccls(RED_F+BLU_B); /* Attributes are red on blue. */ ccputs Summary: #include <color.h> /* Color definitions only */ int ccputs(string,color); int string; /* String to Put */ int color; /* Color of String */ Created: 12/29/85 Last Updated: 02/24/86 Author: Bob Pritchett Source (C/A): C Located in: CCPUTS.OBJ Requires: putchci() Description: This function puts the given string out to the current cursor position in the specified color, using putchci() to do BIOS output. Compiler Specifics: None. Return Value: Nothing. See Also: putchci() Example: #include <color.h> ccputs("This string in red.\n",RED_F); center Summary: int center(row,string); int row; /* Row to Center String on */ char *string; /* String to Center on Screen */ Created: 09/ /85 Last Updated: 02/24/86 Author: Bob Pritchett Source (C/A): C Located in: CENTER.C CENTER.OBJ Requires: gotoxy() prints() Description: This routine will simply center string on line row. An eighty column display is assumed, and the cursor is left at the end of the string. Compiler Specifics: CENTER.OBJ was compiled with MSC 3.0, but there are no other compiler specifics involved. Return Value: Nothing is returned and there are no validity checks. Giving a string longer then 80 characters, or a line number less then zero or greater then 24 will produce an unknown result on screen, while it should return cleanly. See Also: centerf() ccenter() putat() cputat() Example: #include <stdio.h> char *string; scanf("%s",string); center(0,"This line is centered. Centering has a slight"); center(1,"disadvantage with constant text in that the computation is"); center(2,"done at run-time, as opposed to using putat() with a"); center(3,"precalculated center."); center(5,string); centerf Summary: int centerf(row,string[,arguments...]); int row; /* Row to Center String on */ char *string; /* String to Center on Screen */ Created: 04/13/86 Last Updated: 08/17/86 Author: Bob Pritchett Source (C/A): C Located in: CENTERF.OBJ Requires: gotoxy() prints() Description: This routine performs the exact same function as center() with the exception that the string may contain formatting controls which are proccessed according to the same rules as printf() before the string is centered. Up to 15 formatting arguments may be used per string. Compiler Specifics: None. Return Value: Nothing returned, nor are coordinates checked, but be careful to make sure the formatted string will be less then 80 characters long. See Also: center() ccenter() putat() cputat() Example: #include <stdio.h> char *string; printf("What is your name? "); scanf("%s",string); centerf(4,"The answer is: %04d",243); centerf(7,"Hello, %s, nice to meet you.",string); cfield Summary: int cfield(chr,clr,tms); int chr; /* Character to Use in Field */ int clr; /* Attribute to Use for Field */ int tms; /* Length of the Field */ Created: 09/25/86 Last Updated: 09/25/86 Author: Bob Pritchett Source (C/A): A Located in: CFIELD.OBJ Requires: Nothing. Description: This routine is a special assembly routine to create fields for the field input routines. Given the fill character, attribute, and length of the field it will create the field without moving the cursor. No checking of parameters is done. Compiler Specifics: None. Return Value: Nothing is returned. See Also: finptstr() Example: #include <color.h> cfield('*',WHT_F+BLU_B,10); /* Ten character white on */ /* blue asterisk field. */ chk_date Summary: int chk_date(m,d,y); int m; /* Month of Date to Check */ int d; /* Day of Date to Check */ int y; /* Year of Date to Check */ Created: 12/27/85 Last Updated: 12/27/85 Author: Bob Pritchett Source (C/A): C Located in: CSRDATE.OBJ Requires: num_days() Description: This routine verifies that the day and month of the given date are legitimate values. The year is needed in order to check for leapyears. Compiler Specifics: None. Return Value: The function evaluates true if the date is valid, false if it is not. See Also: valid_date() num_days() dt_diff() Example: if ( chk_date(6,15,1500) ) /* Evaluates True */ function(); chline Summary: int chline(x,y,y2,type); int x; /* Upper Left Row */ int y; /* Upper Left Col */ int y2; /* Lower Right Col */ int type; /* Style of Border */ Created: 03/03/86 Last Updated: 03/03/86 Author: Bob Pritchett Source (C/A): C Located in: COUTPUT.OBJ Requires: putchci() gotoxy() Description: This function will draw a line at x,y to x,y2 using the character(s) specified in type. Type may be any one of the five types accepted by box(). Usually this function is used to draw lines inside boxes, as it will use the proper side characters, but by using an ASCII character in type an ordinary line of that character is drawn. The line is drawn in the current color, as specified by color(). Compiler Specifics: None. Return Value: Returns a one if successful, a negative one if invalid coordinates are passed. See Also: cvline() whline() Example: #include <color.h> /* Just for the colors... */ color(RED_F,WHT_B); /* Red on White */ cbox(5,5,20,60,1); /* A box with a single line border */ chline(5,7,60,1); /* Draws a line across the box */ cls Summary: int cls(); Created: 12/28/85 Last Updated: 08/20/86 Author: Bob Pritchett Source (C/A): A Located in: CLS.OBJ Requires: Nothing. Description: This function clears the screen and sends the cursor to the home position using the video BIOS interrupt. Compiler Specifics: Microsoft's assembly header information. Return Value: Nothing. See Also: ccls() wcls() Example: cls(); color Summary: #include <color.h> /* For Color Definitions Only */ int color(attr) int attr; /* Color Attributes */ Created: 03/03/86 Last Updated: 08/06/86 Author: Bob Pritchett Source (C/A): C Located in: COUTPUT.OBJ Requires: Nothing. Description: This routine sets the colors to be used in all following operations involving color in the windows package, unless otherwise specified. In version 1.0 color() required two arguments, the fore and background attributes. To maintain compatibility with other <x>color() routines, there is now only one argument, with the attributes added together. If color()'s argument is -1, it returns the current value for color operations. This is useful if you wish to write windowing functions that restore the current color attributes after opening their own windows. Compiler Specifics: None. Return Value: The color is returned. See Also: wcolor() mcolor() Example: #include <color.h> color(RED_F+BOLD+BLU_B); /* Bold Red on Blue. */ current_page Summary: int current_page(); Created: 02/22/86 Last Updated: 02/24/86 Author: Bob Pritchett Source (C/A): C Located in: CURSOR.OBJ Requires: int86() Description: This function returns the current active video page.

The path must be a standard DOS path name (without file name), using two backslashes instead of one. If the path to search is the root, use the path string of "". The attribute specified in attr is the attribute to use in the search. If none is specified, then only files are reported. If the volume attribute is used, the volume label is returned. If the sub-directory attribute is specified, all files AND sub- directories are returned. The same applies to the hidden and and system attributes, but the archive and read-only attributes can not be used in searches. After a file is found it's data is placed in buf (consult CSRDOS.H for the DIRS structure). The entry type may be determined by & ing the returned attribute and the attribute you wish to test for, as in if ( buf.attr & SUBDIR ) would be true if the entry was a subdirectory.

The default string may be returned with a carriage return as the first character, it may be editted with the left and right arrow keys and ins and del, the field may be erased with the Alt-X combination, and the default input can be restored with the Alt-D combination. Editting is performed with the ins and del keys in combination with movement by the left and right arrow keys. The insert key will toggle insert 'mode' on and off, although the cursor will not reflect the mode change. When in insert mode all characters to the right of the cursor will move right (and possibly scroll out of the field) when characters are inputted. The del key will erase the character the cursor rests on and move everything to the right of the cursor left one space. In order to allow for design of full input screens the function will return with the input in the appropriate location and the value of the key as the return value if one of several extended function keys is entered. These special keys are any use of a function key or keys, other than left and right arrows, on the numeric keypad. (Home, up, down, end, PgUp, PgDn.) (NOTE: Steps were taken to make this function as flexible as possible. However, in most cases requiring complicated input the peculiarities of this and related functions will damage their usefullness. If you need to make use of this type of function in an 'error proof' application it is recommended that you contact the author about getting a special routine or the source code to this one.)

Description: This function acts in the same manner as inptstr() with the exception that a default string may be specified, and at the choice of the user this string may be returned instead of a user entered string. When the function is called the default string is displayed immediately following the prompt, and the cursor is placed at the first character of the string. If a carriage return is entered as the first inputted character, the default string is returned. Any other key causes the default string to be erased and a user entered string may be inputted. Compiler Specifics: None. Return Value: The character string inputted, or the default string.

Description: This function returns a single integer value, the number of logical drives available. Remember that although this function returns the number of available drives, access to these drives is numbered from zero, so if 3 drives are reported, the highest number that may be accessed is 2. Compiler Specifics: None. Return Value: The total number of logical drives installed. See Also: get_drive() set_drive() Example: printf("%d drives installed.

Description: This function will display a pop up menu and allow for selection of an item with the arrow keys, or the space and backspace keys. The differences between pmenu() and pop_menu() are mostly in the calling method. By using a data element of the MENU type as the only argument, the number of parameters specifiable is increased, allowing for better control of the menu, while the number of function arguments is reduced to one for cleaner coding. If the first character in an item name is a hyphen, the item will be a horizontal line of the border color and type. If the return value of an element is a negative one, the item is non selectable. Note, unlike pop_menu(), pmenu() will center the text of each entry to the width of the largest entry. If you place a space on each side of only the largest (widest) entry in a menu structure, all menu options will have at least one space on each side. For information on specification of menus, read the description of CSRMENU.H. Compiler Specifics: None. Return Value: The value of the menu item selected or a -1 for failure. See Also: pop_menu() pmenu Example: #include <csrmenu.h> #include <color.h> MENU mnu; main() { int x; strcpy(mnu->title,"Menu"); mnu->type = 3; mnu->border = WHT_F+BLU_B; mnu->normal = RED_F+WHT_B; mnu->bar = WHT_F+RED_B; mnu->row = 6; mnu->col = 20; mnu->num = 4; strcpy(mnu->entry[0].text,"Help"); mnu->entry[0].value = 1; strcpy(mnu->entry[1].text,"Exit"); mnu->entry[1].value = 2; strcpy(mnu->entry[2].text,"-"); mnu->entry[2].value = -1; strcpy(mnu->entry[3].text," Static "); mnu->entry[3].value = -1; x = pmenu(mnu); if ( x == -1 ) exit(1); else if ( x == 1 ) help(); else exit(0); . . . } pop_menu Summary: int pop_menu(x,y,num,args,title,type); int x; /* Row to Start on */ int y; /* Col to Start on */ int num; /* Number of Options */ char *args[]; /* Function Names */ char *title; /* Menu Title */ int type; /* Window Type */ Created: 03/09/86 Last Updated: 03/09/86 Author: Bob Pritchett Source (C/A): C Located in: COUTPUT.OBJ Requires: wopen() wclose() wtitle() Description: This function opens a window at x,y titled with the string pointed to by title, of type border style, and with num options stored in args[]. The window's width is the size of the maximum length option. The options are printed as sent to the routine, but for a clean highligh bar, and better performance all the options should be centered previously in a string. See the demo programs for more examples of this. Also note, after an option is selected with the highlight bar, the it's number is returned, and the window closed. You must reopen the menu, this preferably done in a loop[ structure that opens the menu, processes the resulting code, and then reopens the menu. This system is a simple building block for more advanced menu design. Compiler Specifics: See window notes. Return Value: The number of the option selected with the highlight bar, or a -1 signifying the user aborted the menu with the ESC key.

Copyright 1985, 1986 Bob Pritchett New Dimension Software Version 2.1 - Documentation CheckC has come quite some distance since version 1.3 was released with the first version of C Spot Run. It now supports an analysis mode with full error recovery, and is better implemented over all. CheckC started as a simple bracket counter type program, checking to make sure brackets, quotes, etc, all were present in even numbers. And the present time it can analyze a file and report syntactical errors to, on average, within two lines, and then recover in order to find any subsequent errors, assuming the one just found was corrected. CheckC may be invoked with as many file names as DOS allows, and will check each one in order for matching pairs of all relevant characters, quotes, and comments. The real power is displayed when it is invoked with a /A as the first argument, followed by the file names. In this case a rather comprehensive (for a character oriented program) syntax check will be executed, with errors and problem spots reported in the format of line number followed by error description. CheckC knows when to and when not to be checking syntax. While in comments, everything but an end of comment is ignored. (NOTE! CheckC does NOT allow for nested comments, in accordance with K&R.) The same applies to quoted strings, with the added contitions that CheckC is aware of when to ignore quotes (as in escape sequences), and when they may be missing. (When a newline is found in a quoted string a warning is generated indicating that further analysis may be incorrect.) Single quotes are processed under the rule that only one character is allowed between them, the maximum physical characters being two in the case of an escape sequence. CheckC's analysis will sometimes refer to errors concerning functions or blocks. CheckC refers to any code one bracket level deep as a function, and any code several brackets deep as a block. Unfortunatly, as you may open a virtually unlimited number of blocks, a missing open bracket can only be detected when the number of closing brackets exceeds the number of opening ones. In such a case an error is noted, the missing character assumed, and analysis continued. By noting funtion vs. block in the error, and tracing structured code up from the line number, the missing (or extra) bracket can easily be found. Another way of finding mismatched characters as soon as possible is looking for semicolons within them. Anytime a semicolon is found within a set of parenthesis or square brackets, chances are that there is a missing closing character within a few lines of it. (Semicolons within for() statements will not cause this error flag.) If a comment is left open, causing the rest of the file to go un-analyzed, a line number will be reported with the error at when end of file is reached. This is the line on which last found comment was opened, and from there the error should be obvious. On the whole, CheckC's errors are self explanatory, and in all testing so far it has been perfectly accurate. It is much more likely to report a few extra errors when recovery is not complete then to miss any. Without the analysis mode it is severly crippled, and it is recommended that you use the /A flag with everything unless your code varies from K&R enough to cause false errors. I'd appreciate it if you could report any bugs or suggestions, and let me know how you like it. Good luck! FLine Summary: Created: 03/02/86 Last Updated: 03/03/86 Author: Bob Pritchett Source: C Syntax: FLine <source> <dest> Documentation: FLine A Structured Programming Utility Copyright 1986 Bob Pritchett New Dimension Software Version 1.1 - Documentation FLine is a programming tool that goes through source code and places all lines beginning with a non-whitespace character into the specified output file. This creates a useful reference file containing a list of all function declarations, including arguments, global variables, comments, and pre-processor directives. (This assumes, of course that you indent the actual code within your source file.) FLine is called as: FLine <source> <dest> Where <source> is the source code to process and <dest> is the name of the file to place the output in. Note that whatever is in <dest> is erased and replaced with FLine's output. CSRSHELL.ASM Summary: Created: 09/10/86 Last Updated: 09/10/86 Author: Various Documentation: CSRShell.ASM is a small file that contains a complete shell for writing assembly interfaces to Microsoft C. (In the planning stages are additions for contitional assembly for other compilers.) Things such as large and small model assembly, argument reading, stack setup and more are included and explained. To make use of the shell, copy it into another appropriately named file, insert the correct function name over _shell (remember to preserve the underscore, MSC needs it), replace the two dummy argument reads with your assembly source, and place your data in the appropriate place. COLOR.H Summary: Created: 04/14/86 Last Updated: 09/20/86 Author: Bob Pritchett Description: This include file contains the define statements for all the color attributes possible in text. The colors are listed with a three letter name followed by a _ and F or B signifying fore or background attribute. To get a full attribute, add a fore and background color. (BLU_F+RED_B) Also included are definitions for BOLD (which is added to an attribute to intensify it), NORMAL (white on black), and several others. (NOTE: Some of the attriutes are for monochrome displays only, for example, UNDERLINE shows as blue on a color screen, and REVERSE as black on white.) For a list of all the colors and their abbreviations look at the header file. CSRDOS.H Summary: Created: 04/04/86 Last Updated: 04/04/86 Author: Bob Pritchett and Alan Losoff Description: This header file contains structures and #define statements needed by functions accessing DOS 2.0 functions. CSRMENU.H Summary: Created: 08/08/86 Last Updated: 08/16/86 Author: Bob Pritchett Description: This header file contains the typdef statement to create the MENU data type needed for the function pmenu(). The structure is as follows: typedef struct _mnu { char title[23]; /* Title of the menu */ int type; /* Style of the border */ int border; /* Window's border color */ int normal; /* Color for unhighlighted items */ int bar; /* Color for the highlight bar */ int row; /* Upper left window row */ int col; /* Upper left window column */ int num; /* Number of enteries */ struct _ent { char text[25]; /* Item's name */ int value; /* Return value for item / -1 Static */ } entry[MAX_ENTRIES]; } *MENU; CSRMISC.H Summary: Created: 04/20/86 Last Updated: 12/05/86 Author: Bob Pritchett Description: This header file contains dummy(), iswild(), and the defintions for the min() and max() macros which were ommitted from Microsoft's standard library. CSRMODES.H Summary: Created: 05/05/86 Last Updated: 05/05/86 Author: Bob Pritchett Description: This header file contains define statements for the different video modes. It is intended to be used with set_mode(). CSRSOUND.H Summary: Created: 08/07/86 Last Updated: 08/07/86 Author: Bob Pritchett (Data from Norton's Book.) This header file contains note definitions for use with the sound() routine in CSRSOUND.OBJ. CSRTIME.H Summary: Created: 05/05/86 Last Updated: 04/20/86 Author: Bob Pritchett This file contains two static char * arrays containing the names of the days of the week and the days of the month. The days of the week start with Sunday, the months start with a null and then January as the second entry, element one, to allow compatibility with the way DOS returns the date. ERRORS.H Summary: Created: 05/05/86 Last Updated: 05/05/86 Author: Bob Pritchett (Data from Norton's Book.) This file contains a static char * array containing the DOS errors returned in AX after a DOS function call. These errors are for DOS 2.X alone, and do not apply to DOS 3.X extended error codes. Error descriptions start with element one. SKEY.H Summary: Created: 02/22/86 Last Updated: 02/22/86 Author: Bob Pritchett (Data from Norton's Book.) Description: This header file contains #define statements for all of the special keys and combinations on the keyboard. These values are those returned as extened codes, after a null is read. They are in the basic format of KEY1KEY2, or simply Fx for function keys. (Note: Function keys are numbered through 40, 1-10 are normal keys, 11-20 are shift keys, 21-30 are ctrl keys, and 31-40 are alt keys. As in Shift-F2 returns F12.) C Spot Run - Documentation Appendix A - Updating the Library The C Spot Run routine library is constantly being added to as we receive contributions and write more routines ourselves. In the interest of saving time and space, library updates will come in one of two forms. First, small collections of new routines, or single routines, will be placed in archives along with a single page of documentation and distributed via BBSs. Registered users will receive information about new updates or a copy of those updates. When you receive an update archive you simply place the files into your library or linking directory and print out the documentation page, which is then inserted in alphabetical order into the library description section of this manual. (This is why those pages are not numbered and we recommend storing your manual in a three ring binder.) Second, major updates to the entire library will be distributed in archives containing all the routines, and a totally new version of the complete manual. These updates will be on new version numbers. To keep on top of changes to the library it is suggested that you read issues of the C Spot Run Newsletter as it is released, and make an occasional call to the support BBS where the latest version of the library and newsletter are always available. C Spot Run - Documentation Appendix B - Contacting Authors Each description page mentions the name of the author of that routine, utility, or aid. If for some reason you would like to contact that author you may check the following directory for addresses and possibly phone numbers. (NOTE: All of the following authors voluntarily placed their addresses and sometimes their phone numbers in this directory. They have indicated a willingness to answer questions by doing this, but we ask you to be considerate with you calling hours and keep in mind differences in time zones.) Mongelluzzo, Philip A.
