SelectClipPath

The SelectClipPath function selects the current path as a clipping region for a device context, combining the new region with any existing clipping region by using the specified mode.

BOOL SelectClipPath(
  HDC hdc,    // handle of device context
  int iMode   // clipping mode
);
 

Parameters

hdc

Handle to the device context of the path.

iMode

Specifies the way to use the path. The following values are allowed:

Value	Meaning
RGN_AND	The new clipping region includes the intersection (overlapping areas) of the current clipping region and the current path.
RGN_COPY	The new clipping region is the current path.
RGN_DIFF	The new clipping region includes the areas of the current clipping region with those of the current path excluded.
RGN_OR	The new clipping region includes the union (combined areas) of the current clipping region and the current path.
RGN_XOR	The new clipping region includes the union of the current clipping region and the current path but without the overlapping areas.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero.

WindowsNT: To get extended error Information, call GetLastError. GetLastError may return one of the following error codes:

ERROR_CAN_NOT_COMPLETE
ERROR_INVALID_PARAMETER
ERROR_NOT_ENOUGH_MEMORY

Remarks

The device context identified by the hdc parameter must contain a closed path.
