unsigned short OSqhead (unsigned short *dummy, void *Queue);

Gets an element from the head of a queue.

OSqhead returns an element from the head of a queue structure pointed to by Queue without removing it from the queue (the head element is the last element inserted in the queue, not the first one). dummy is the dummy parameter: it is not used in the routine.
