Syntax
int ReleaseDC( HWND hWnd, HDC hDC);
Parameters
hWnd
Handle to the window whose device context is to be released.
hDC
Handle to the device context to be released.
Return Values
The return value specifies whether the device context is released. 1 indicates that the device context is released. Zero indicates that the device context is not released.
Remarks
The application must call the ReleaseDC function for each call to the GetWindowDC function and for each call to the GetDC function that retrieves a common device context.
An application cannot use the ReleaseDC function to release a device context that was created by calling the CreateDC function; instead, it must use the DeleteDC function.
