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.
