NAME
       TRACE - Debugging helper macro to trace messages. Allegro game program‐
       ming library.

SYNOPSIS
       #include <allegro.h>

       void TRACE(char *msg, ...);

DESCRIPTION
       Debugging helper macro. Normally compiles away to nothing, but  if  you
       defined	the  preprocessor  symbol  DEBUGMODE  before including Allegro
       headers, it passes the  supplied	 message  given	 in  ASCII  format  to
       al_trace().  Example:

	  #define DEBUGMODE
	  #include
	  ...
	  void my_blitter(BITMAP *source, int flags)
	  {
	     static int count_call = 0;
	     TRACE("my_blitter() called %d times.\n", count_call++);
	     ...
	  }

SEE ALSO
       al_trace(3), ASSERT(3), register_trace_handler(3)
