A pointer to an indicator that specifies whether
to start at the beginning of the queue or at a particular element.
Possible values are described in the following list:
Set by the application to indicate "examine the first
element in the queue," according to the order that was specified when the
queue was created (FIFO, LIFO, or priority).
Any Other Value
Set by the DosPeekQueue function
to identify the element that has been examined (output), or by the owner
to indicate "examine the next element" (input).
Note:
By contrast, when a DosReadQueue
request follows DosPeekQueue, DosReadQueue
removes the same element that is identified by element, not the
next element in the queue.
