install_timer(3)                Allegro manual                install_timer(3)

NAME
       install_timer - Installs the Allegro timer interrupt handler.

SYNOPSIS
       #include <allegro.h>

       int install_timer();

DESCRIPTION
       Installs the Allegro timer interrupt handler. You must do this before
       installing any user timer routines, and also before displaying a mouse
       pointer, playing FLI animations or MIDI music, and using any of the GUI
       routines.

RETURN VALUE
       Returns zero on success, or a negative number on failure (but you may
       decide not to check the return value as this function is very unlikely
       to fail).
