Operating Systems Supported |

Requires Windows NT 3.1 or later; Requires Windows 95 or later |
- hWnd
Identifies the window that owns the caret.
- hBitmap
Identifies the bitmap that defines the caret shape. If this parameter is NULL, the caret is solid. If this parameter is (HBITMAP) 1, the caret is gray. If this parameter is a bitmap handle, the caret is the specified bitmap. The bitmap handle must have been created by the CreateBitmap, CreateDIBitmap, or LoadBitmap function.
If hBitmap is a bitmap handle, CreateCaret ignores the nWidth and nHeight parameters; the bitmap defines its own width and height.
- nWidth
Specifies the width of the caret in logical units. If this parameter is zero, the width is set to the system-defined window border width. If hBitmap is a bitmap handle, CreateCaret ignores this parameter.
- nHeight
Specifies the height, in logical units, of the caret. If this parameter is zero, the height is set to the system-defined window border height. If hBitmap is a bitmap handle, CreateCaret ignores this parameter. |
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError. |
