The ReleaseDC function releases the given device context, freeing it for use by other applications.
hwnd
Identifies the window whose device context is to be released.
hdc
Identifies the device context to be released.
The return value is 1 if the function is successful. Otherwise, it is 0.
The effect of ReleaseDC depends on the type of device context. It frees only common and window device contexts. It has no effect on class or private device contexts.
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.
