- PMDEBUG
- -------
-
- PMDEBUG is a program which collects queue input and writes it to its main
- window on a TTY style basis. The program is a PM program, but the collection
- of queue messages is not PM dependant, so logging much debug information
- won't block the message passing within the PM. The program has two functions:
-
- debug_puts(char *txt)
-
- A function like puts() to stdout, just puts TTY like output to the PMDEBUG
- window, which acts as stdout. This function can be used by any OS/2 program,
- PM or non-PM.
- In the TEST.C sample program is an example in which printf() is to be
- rerouted to the PMDEBUG window. This also works under non-PM programs.
-
- debug_logmessage(HWND hwnd, USHORT msg, MPARAM mp1, MPARAM mp2, char far *txt)
-
- This function is useful to examine which messages there are actually passing
- to your PM program. The TXT parameter can just be used for comment.
-
- These functions just use DosOpenQueue() and when this function fails (PMDEBUG
- is not loaded) it returns immediately to the caller.
- Otherwise it creates a shared memory segment available to the server
- (PMDEBUG) and performs DosWriteQueue(). This is considerably less
- time-consuming than message passing by WinSendMsg() and is available to
- non-PM programs too. PMDEBUG performs a DosReadQueue() with wait in a
- separate thread, so its window procedure only repaints and waits for
- keyboard/mouse input.
- The entire screen is saved in a buffer, so maximizing the window will show
- the last page.
- PMDEBUG also logs all incoming text to a file called LO. The filename can be
- changed.
- Keyboard Input :
-
- d deletes the current log file.
- l turns loggin off and on, when turned on, output will be appended to the
- current log file.
- F1 or ?
- shows a little help box
- F3 or Ctrl-C
- exits PMDEBUG.
-
- Command line switches:
-
- PMDEBUG -1 loads small (6x8 pixels) font.
- PMDEBUG -f <file> logs to <file> rather than LO.
-
- The file SEEFONTS.DLL provides two fonts because the fonts provided with PM
- are too large to get much information on a 'normal' VGA screen and are only
- useful on a 800x600 or higher resolution screen.
-
- The routine PMDEBFUN.C contains code which you should add to your program to
- enable debug output to the PMDEBUG window. The program TEST is a sample PM
- program which printf-s to PMDEBUG.
-
- Another feature of PMDEBUG:
- It uses a color icon instead of a normal monochrome PM icon in OS/2 1.1. The
- code for it is in PMDEBUG.C.
