Remarks

MouSetDevStatus is the complement to MouGetDevStatus. However, not all status flags may be set with MouSetDevStatus. Only the flags corresponding to the following functions may be modified:

• Return data in mickeys.
  • Normally, mouse data is returned to the application with the absolute display mode coordinates of the pointer image position on the display screen. By setting this status flag, mouse data is returned in relative mickeys, a unit of mouse movement.
• Don't call pointer draw device.
  • Normally, the pointer draw device driver is called for all drawing operations. By setting this status flag, the mouse device driver does not call the pointer draw device driver. The application must draw any required pointer image on the screen.
