MouRemovePtr

Bindings:  C, MASM 

This call allows a process to notify the mouse device driver that the area 
defined by the passed parameters is for the exclusive use of the 
application.  This area is defined as the collision area and is not 
available to the mouse device driver when drawing pointer images.

       Upper left column coordinate (pels or characters). 

    rightrow (USHORT)

 Remarks 

 MouRemovePtr may be issued by any process in the session. However, only 
 one collision area is active at a time. Each MouRemovePtr command has the 
 effect of resetting the collision area to the location and area specified 
 by the current command. 

 If the logical pointer position is outside of the collision area 
 specified by the latest MouRemovePtr command, the pointer image is drawn. 
 

 The MouDrawPtr command effectively cancels the  MouRemovePtr command and 
 allows the pointer to be drawn anywhere on the screen, until a new 
 MouRemovePtr command is issued.
