NAME

       al_register_trace_handler - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              void al_register_trace_handler(void (*handler)(char const *))

DESCRIPTION

       Register  a  callback  which is called whenever Allegro writes something to its log files.
       The default logging to allegro.log is disabled while this callback is active.   Pass  NULL
       to revert to the default logging.

       This function may be called prior to al_install_system.

       See  the  example  allegro5.cfg  for  documentation  on  how  to  configure the used debug
       channels, logging levels and trace format.
