Revision as of 17:28, 14 September 2019 by Ak120 (talk | contribs)

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.
