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).
