al_run_main (3alleg5)

• #include <allegro5/allegro.h>
  
  int al_run_main(int argc, char **argv, int (*user_main)(int, char **))
  
  

This function is useful in cases where you don\[aq]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\[aq]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.
