short OSdequeue (unsigned short *dest, void *Queue);

Removes an element from a queue.

OSdequeue removes an element from a queue structure pointed to by Queue and stores them in the variable pointed to by dest. As queue is a FIFO structure, first removed element is the first element inserted in the queue; the next removed element is the second element inserted in the queue, etc. OSdequeue returns TRUE if the queue was empty, else returns FALSE.
