poll_joystick(3alleg4) Allegro manual poll_joystick(3alleg4)NAME
poll_joystick - Polls the joystick. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
int poll_joystick();
DESCRIPTION
The joystick handler is not interrupt driven, so you need to call this function every now and again to update the global position values.
Example:
do {
/* Get joystick input */
poll_joystick();
/* Process input for the first joystick */
if (joy[0].button[0].b)
first_button_pressed();
if (joy[0].button[1].b)
second_button_pressed();
...
} while(!done);
RETURN VALUE
Returns zero on success or a negative number on failure (usually because no joystick driver was installed).

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
