// Useful macros based on some DNet code (which was taken from code by ToddLa)
//==================================================================================
//
// Macros that generate compile time messages. Use these with #pragma:
//
// #pragma TODO(vanceo, "Fix this later")
// #pragma BUGBUG(vanceo, "Busted!")
// #pragma PRINTVALUE(DPERR_SOMETHING)
//
// To turn them off, define TODO_OFF, BUGBUG_OFF, PRINTVALUE_OFF in your project
// preprocessor defines.
//
//
// If we're building under VC, (as denoted by the preprocessor define
// DPNBUILD_ENV_NT), these expand to look like:
//
// D:\directory\file.cpp(101) : BUGBUG: vanceo: Busted!
//
// in your output window, and you should be able to double click on it to jump
// directly to that location (line 101 of D:\directory\file.cpp).
//
// If we're building under the NT build environment, these expand to look like:
//
// BUGBUG: vanceo: D:\directory\file.cpp(101) : Busted!
//
// because (at least right now) the build process thinks that a failure occurred if
// a message beginning with a filename and line number is printed. It used to work
// just fine, but who knows.

/*=============================================================================
Usage:
In code, you can use DPF to print to the log or the debug windows of the running application. The format of DPF (debug printf) is as follows:
DPFX(DPFPREP,level, string *fmt, arg1, arg2, ...);
level specifies how important this debug printf is. The standard convention for debug levels is as follows. This is no way strictly enforced for personal use, but by the time the code is checked in, it should be as close to this as possible...
DPF_ERRORLEVEL: Error useful for application developers. DPF_WARNINGLEVEL: Warning useful for application developers. DPF_ENTRYLEVEL: API Entered DPF_APIPARAM: API parameters, API return values DPF_LOCKS: Driver conversation DPF_INFOLEVEL: Deeper program flow notifications DPF_STRUCTUREDUMP: Dump structures DPF_TRACELEVEL: Trace messages
When printing a critical error, you can use: DPERR( "String" );
which will print a string at debug level zero.
In order to cause the code to stop and break in. You can use ASSERT() or DEBUG_BREAK(). In order for ASSERT to break in, you must have BreakOnAssert set in the win.ini file section (see osindep.cpp).
