 MouSetEventMask     (EventMask, DeviceHandle) 
 

 EventMask (PUSHORT) - input 
    Address of a value in application storage used to indicate what mouse 
    events are to be placed on the event queue (see MouReadEventQue) and 
    which events are to be ignored. 

    The EventMask bit values are described below: 

    Bit       Description 
    15-7      Reserved, set to zero. 
    6         Set to report button 3 press/release events, without mouse 
              motion 
    5         Set to report button 3 press/release events, with mouse 
              motion 
    4         Set to report button 2 press/release events, without mouse 
              motion 
    3         Set to report button 2 press/release events, with mouse 
              motion 
    2         Set to report button 1 press/release events, without mouse 
              motion 
    1         Set to report button 1 press/release events, with mouse 
              motion 
    0         Set to mouse motion events with no button press/release 
              events. 

   
    A bit clear setting (set to zero) in an EventMask bit position 
    indicates that the associated type of event is not reported to the 
    application. Note also that the mouse buttons are always numbered from 
    left to right. When the mouse is properly positioned for use, the 
    left-hand button is button 1. 

 DeviceHandle (HMOU) - input 
    Handle of the mouse device from a previous MouOpen.

    501       ERROR_MOUSE_NO_CONSOLE 
    505       ERROR_MOU_EXTENDED_SG 
 
 Remarks 

 Setting a bit in the event mask means that the associated event is 
 reported on the mouse FIFO event queue.  See MouReadEventQue for examples 
 of event mask use.
