Notifies the mouse device driver that an area previously restricted by MouRemovePtr is now available to the mouse device driver when drawing pointer images.
Syntax
MouDrawPtr(DeviceHandle)
Parameters
- DeviceHandle (HMOU) - input
- Mouse device handle.
- Reserved. Must be 0.
- rc (APIRET) - returns
- Return code:
- 0 NO_ERROR
- 466 ERROR_MOU_DETACHED
- 501 ERROR_MOUSE_NO_CONSOLE
Remarks
MouDrawPtr is required to begin a pointer-image drawing session. At session start, the collision area (the area restricted from pointer-image drawing) is defined as the size of the display.
After a call to MouDrawPtr, MouRemovePtr can be used to define a new collision area. A subsequent call to MouDrawPtr will cancel the collision area.
