rest_callback(3alleg4)                                            Allegro manual                                            rest_callback(3alleg4)

NAME
       rest_callback - Like rest(), but calls the callback during the wait. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       void rest_callback(long time, void (*callback)())

DESCRIPTION
       Like  rest(),  but for non-zero values continually calls the specified function while it is waiting for the required time to elapse. If the
       provided `callback' parameter is NULL, this function does exactly the same thing as calling rest().
