TRACE(3)                        Allegro manual                        TRACE(3)



NAME
       TRACE - Debugging helper macro to trace messages. Allegro game
       programming 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++);
             ...
          }
