| 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. | 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.

| 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. | MouRemovePtr may be issued by any process in the session.

| 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. | 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. | ||
