NtGdiDdReleaseDC function

[This function is subject to change with each operating system revision. Instead, use the DirectDraw and Microsoft Direct3DAPIs; these APIs insulate applications from such operating system changes, and hide many other difficulties involved in interacting directly with display drivers.]

Releases the previously created device context (DC) for the indicated kernel-mode Microsoft DirectDraw surface object.

Syntax

BOOL APIENTRY NtGdiDdReleaseDC(
  _In_ HANDLE hSurface
);

Parameters

hSurface [in]

Handle to the previously created kernel-mode DirectDraw surface object.

Return value

If successful, this function returns TRUE; otherwise it returns FALSE.

Remarks

Applications that need to obtain a DC for a DirectDraw surface may use IDirectDrawSurface7::GetDC, which exposes this functionality in a manner independent of the operating system.
