NAME
install_int - Installs a user timer handler. Allegro game programming
library.
SYNOPSIS
#include <allegro.h>
int install_int(void (*proc)(), int speed);
DESCRIPTION
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.
RETURN VALUE
Returns zero on success, or a negative number if there is no room to
add a new user timer.
