16 Debugging helper macro. Normally compiles away to nothing, but if you
17 defined the preprocessor symbol DEBUGMODE before including Allegro
18 headers, it passes the supplied message given in ASCII format to
19 al_trace(). Example:
20
21 #define DEBUGMODE
22 #include
23 ...
24 void my_blitter(BITMAP *source, int flags)
25 {
26 static int count_call = 0;
27 TRACE("my_blitter() called %d times.\n", count_call++);
28 ...
29 }
