al_trace(3alleg4)                Allegro manual                al_trace(3alleg4)



NAME
       al_trace - Outputs a debugging trace message. Allegro game programming
       library.

SYNOPSIS
       #include <allegro.h>


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

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