/********************************************************************
|
|
|
|
Setting up the debug support:
|
|
=============================
|
|
|
|
Define a MODULE prefix string. Since this will be printed as
|
|
a prefix to all debug output, it should be concise and unique.
|
|
|
|
In your global header file:
|
|
|
|
#define MODULE "prtlib:"
|
|
|
|
Define a MODULE_DEBUG variable. This is the actual symbol
|
|
that the library will use to indicate debugging level.
|
|
This DWORD is broken into two bitfield WORDs: the low word
|
|
indicates which levels to print to the debugger; the high word
|
|
breaks into the debugger. The library takes the DebugLevel from
|
|
a debug message, then ANDs it with the debug level. If the bit
|
|
is on, the corresponding action (print or break) is taken.
|
|
|
|
In your global header file:
|
|
|
|
#define MODULE_DEBUG PrtlibDebug
|
|
|
|
Finally, the actual debug variable must be defined and initialized
|
|
to a default debug level. This must be done in exactly one
|
|
*.c translation unit:
|
|
|
|
In one of your source files:
|
|
|
|
MODULE_DEBUG_INIT ( {LevelsToPrint}, {LevelsToBreak} );
|
|
|
|
Adding logging to source code:
|
|
==============================
|
|
|
|
The general format for debug message is:
|
|
|
|
DBGMSG( {DebugLevel}, ( {args to printf} ));
|
|
|
|
The DebugLevel dictates whether the level should print, break
|
|
into the debugger, or just log to memory (logging always done).
|
|
|
|
The args to printf must be placed in an extra set of parens,
|
|
and should assume everything is ANSI. To print LPTSTRs, use
|
|
the TSTR macro:
|
|
|
|
DBGMSG( DBG_WARN,
|
|
( "LPTSTR "TSTR", LPSTR %s, LPWSTR %ws\n",
|
|
TEXT("hello"), "hello", L"hello" ));
|
|
|
|
Viewing DBGMSGs:
|
|
================
|
|
|
|
Messages will print to the debugger (usermode, or kernel debugger
|
|
if no usermode debugger is available) for all printable levels.
|
|
To change the level, you can edit the MODULE_DEBUG variable
|
|
(PrtlibDebug in the above example).
|
|
|
|
By default, DBG_ERROR and DBG_WARNING messages a logged to the
|
|
error log (stored at gpbterrlog). All others are stored in the
|
|
trace log (gpbttracelog). These currently log to memory in
|
|
a circular buffer. Use the splx.dll extension to dump these
|
|
logs.
|
|
|
|
At compile time, you can switch these logs to go to file rather
|
|
than memory. They will be stored as the PID + index number in
|
|
the default directory of the process.
