View source for MouDrawPtr

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==
 #define INCL_MOU
 #include <os2.h>
 
 HMOU      DeviceHandle;  /*  Mouse device handle. */
 APIRET    rc;            /*  Return code. */ 
 
 rc = MouDrawPtr(DeviceHandle);

==Parameters==
;DeviceHandle (HMOU) - input :Mouse device handle.
:Reserved. Must be 0.

===Return code===
 rc (APIRET) - returns
MouDrawPtr returns one of the following values:
* 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.
