The WinCreatePointer function creates a pointer from a bitmap.
 
Parameter    Description
────────────────────────────────────────────────────────────────────────────
 
hwndDesktop  Identifies the desktop window. This parameter can be
             HWND_DESKTOP or the desktop window handle.
 
hbmPointer   Identifies the bitmap from which the pointer image is created.
             The bitmap must be of an even vertical size, logically divided
             into two sections in the vertical direction, each half
             representing one of the two images used as the successive
             drawing masks for the pointer. The top half is the XOR image.
             The bottom half is the AND image. This allows a pointer to have
             four colors: black, white, background, and inverted
             background.
 
fPointer     Indicates if the pointer is pointer- or icon-sized. If this
             parameter is TRUE, the bitmap will be stretched (if necessary)
             to the system-pointer dimensions. If this parameter is FALSE,
             the bitmap will be stretched (if necessary) to the system-icon
             dimensions.
 
xHotspot     Specifies the horizontal offset of the pointer hot spot from
             the lower-left corner (in pels).
 
yHotspot     Specifies the vertical offset of the pointer hot spot from the
             lower-left corner (in pels).
 
Return Value
 
The return value is the handle of the new pointer, or it is NULL if an error
occurs.
 
Comments
 
Since the bitmap needs to include two images, one on top of the other, the
height of the bitmap must be an even number. This function will fail if the
height is not an even number.
