The MOU_READEVENTQUE function reads the event queue for the pointing
device.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
pmeiEvent  Points to the MOUEVENTINFO structure that receives event-queue
           information.
 
pfWait     Points to the variable that specifies how to read from the queue
           if no event is available. If the variable is WAIT, the function
           returns immediately without an event. If the variable is NOWAIT,
           the function waits until an event is available.
 
hDevice    Identifies the pointing device that receives the device-control
           function. The handle must have been created previously by using
           the DosOpen function.
 
Return Value
 
The return value is zero if the function is successful or an error value if
an error occurs.
