install_timer(3alleg4) Allegro manual install_timer(3alleg4)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).

install_int(3alleg4) Allegro manual 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.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it
