  Set one of the options for tweaking some behaviours of capturing. Note that each option only takes effect from after it is set - so it is advised to set these options as early as possible, ideally before any graphics API has been initialised.

  This function is similar to :cpp:func:`EndFrameCapture` but the capture contents will be discarded immediately, and not processed and written to disk. This will be more efficient than :cpp:func:`EndFrameCapture` if the frame capture is not needed.
  :param RENDERDOC_DevicePointer device: is a handle to the API 'device' object that will be set active. May be NULL to wildcard match.
  :param RENDERDOC_WindowHandle wndHandle: is a handle to the platform window handle that will be set active. May be NULL to wildcard match.
