install_int - Man Page

#include <allegro.h>

int install_int(void (*proc)(), int speed);

Installs a user timer handler, with the speed given as the number of  milliseconds between ticks. This is the same thing as  install_int_ex(proc, MSEC_TO_TIMER(speed)). If you call this routine  without having first installed the timer module, install_timer() will be  called automatically. Calling again this routine with the same timer handler as parameter allows you to adjust its speed.

Returns zero on success, or a negative number if there is no room to add a new user timer.
