IDCompositionSurface::EndDraw method (dcomp.h)

Marks the end of drawing on this Microsoft DirectComposition surface object.

Syntax

HRESULT EndDraw();

Return value

Type: HRESULT

If the function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code, which can include DCOMPOSITION_ERROR_SURFACE_NOT_BEING_RENDERED.

Remarks

This method completes an update that was begun by a previous call to the IDCompositionSurface::BeginDraw method. After this method returns, the application can start another update on the same surface object or on a different one.

If the application calls IDCompositionDevice2::Commit before calling IDCompositionSurface::EndDraw for a surface with a pending update, that update is not processed by that Commit call. The update only takes effect on screen after the application calls IDCompositionSurface::EndDraw followed by the IDCompositionDevice2::Commit method.
