.SH NAME
install_int \- Installs a user timer handler. Allegro game programming library.\&
.SH SYNOPSIS
.B #include <allegro.h>

.sp
.B int install_int(void (*proc)(), int speed);
.SH 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.
.SH "RETURN VALUE"
Returns zero on success, or a negative number if there is no room to add
a new user timer.
