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().
