CreateCursor info  Overview  Group

The CreateCursor function creates a cursor having the specified size, bit patterns, and hot spot.

HCURSOR CreateCursor(

    HINSTANCE hInst,

// handle to application instance

    int xHotSpot,

// horizontal position of hot spot

    int yHotSpot,

// vertical position of hot spot

    int nWidth,

// cursor width

    int nHeight,

// cursor height

    CONST VOID *pvANDPlane,

// pointer to AND bitmask array

    CONST VOID *pvXORPlane

// pointer to XOR bitmask array

   );

Parameters

hInst
Identifies the current instance of the application creating the cursor.
xHotSpot
Specifies the horizontal position of the cursorís hot spot.
yHotSpot
Specifies the vertical position of the cursorís hot spot.
nWidth
Specifies the width, in pixels, of the cursor.
nHeight
Specifies the height, in pixels, of the cursor.
pvANDplane
Points to an array of bytes that contains the bit values for the AND bitmask of the cursor, as in a device-dependent monochrome bitmap.
pvXORplane
Points to an array of bytes that contains the bit values for the XOR bitmask of the cursor, as in a device-dependent monochrome bitmap.

Return Values

If the function succeeds, the return value identifies the cursor.

If the function fails, the return value is NULL. To get extended error information, call GetLastError.

Remarks

The nWidth and nHeight parameters must specify a width and height that are supported by the current display driver, because the system cannot create cursors of other sizes. To determine the width and height supported by the display driver, use the GetSystemMetrics function, specifying the SM_CXCURSOR or SM_CYCURSOR value.

Before closing, an application must call the DestroyCursor function to free any system resources associated with the cursor.
