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). SEE ALSO
