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).

SEE ALSO

       remove_timer(3alleg4), install_int(3alleg4)

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.
