// Debug Logging support
//========================

/*=============================================================================
 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:

 DPF(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...

  0: Error useful for application developers.
  1: Warning useful for application developers.
  2: API Entered
  3: API parameters, API return values
  4: Driver conversation
  5: Deeper program flow notifications
  6: Dump structures
  9: Detailed program trace

 Note: please use the DVF_... macros defined above instead of raw numbers!

 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).
