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