  int ReleaseDC( CDC* pDC );
 
  Parameter   Description
 
  <pDC>       Identifies the device context to be released.
 
  Remarks
 
  Releases a device context, freeing it for use by other applications. The
  effect of the ReleaseDC member function depends on the device-context
  type. It only frees common and window device contexts. It has no effect
  on class or private device contexts.
 
  The application must call the ReleaseDC member function for each call to
  the ◄GetWindowDC► member function and for each call to the ◄GetDC►
  member function that retrieves a common device context.
 
  Return Value
 
  Specifies whether the device context is released. It is 1 if the device
  context is released; otherwise 0.
