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(3alleg5). But
  some other system (like OSX) don't allow calling al_install_system(3alleg5) 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.
