MouDrawPtr

Bindings:  C, MASM 

This call allows a process to notify the mouse device driver that an area 
previously restricted to the pointer image is now available to the mouse 
device driver. 

 MouDrawPtr  (DeviceHandle) 
 

 DeviceHandle (HMOU) - input 
    Mouse device handle from a previous MouOpen. 

 rc (USHORT) - return 
    Return code descriptions are: 

    0         NO_ERROR 
    385       ERROR_MOUSE_NO_DEVICE 
    466       ERROR_MOU_DETACHED 
    501       ERROR_MOUSE_NO_CONSOLE 
    505       ERROR_MOU_EXTENDED_SG 
 
 Remarks 

 The collision area (the pointer image restricted area) is established by 
 MouOpen and by MouRemovePtr. MouDrawPtr nullifies the effect of the 
 MouRemovePtr command. If there was no previous MouDrawPtr command or if a 
 previous  MouDrawPtr command has already nullified the collision area, 
 the MouRemovePtr command is effectively a null operation. 

 This call is required to begin session pointer image drawing. Immediately 
 after MouOpen is issued, the collision area is defined as the size of the 
 display. A MouDrawPtr is issued to begin pointer drawing after the 
  MouOpen.
