al_run_main(3)                                                  al_run_main(3)

NAME
       al_run_main - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              int al_run_main(int argc, char **argv, int (*user_main)(int, char **))

DESCRIPTION
       This function is useful in cases where you don't have a main() function
       but want to run Allegro (mostly useful in a wrapper library).  Under
       Windows and Linux this is no problem because you simply can call
       al_install_system(3).  But some other system (like OSX) don't allow
       calling al_install_system(3) in the main thread.  al_run_main will know
       what to do in that case.

       The passed argc and argv will simply be passed on to user_main and the
       return value of user_main will be returned.
