7       library.

SYNOPSIS

10       #include <allegro.h>

13       void al_trace(const char *msg, ...);

DESCRIPTION

16       Outputs a debugging trace message, using a printf() format string given
17       in ASCII. If you have installed a custom trace handler it uses that, or
18       if the environment variable ALLEGRO_TRACE is set  it  writes  into  the
19       file  specified  by the environment, otherwise it writes the message to
20       "allegro.log" in the current directory. You will usually  want  to  use
21       the TRACE() macro instead of calling this function directly.
