The DetectModefunction is used to determine the display mode that corresponds exactly to a set of parameters. The list of supported modes is parsed using GetModeand GetModeEx(if it is supported) in order to find a match.
virtual SCODE DetectMode ( DWORD * dwModeID , DWORD dwWidth , DWORD dwHeight , EGPEFormat format , EDDGPEPixelFormat pixelFormat , DDPIXELFORMAT * pDDPF = NULL );
Parameters
- dwModeID
- Will contain the mode that is detected, based on the selected parameters.
- dwWidth
- The display mode's width.
- dwHeight
- The display mode's height
- format
- The display mode's format.
- pixelFormat
- The display mode's pixel format.
- pDDPF
- The DirectDraw pixel format structure that should be used in
addition to the other parameters for precisely matching a mode. If
this parameter is NULL, it is ignored, and the function relies on
the other parameters to find a match.
Return Values
The return value is S_OK if the function is successful. Otherwise an error code is returned.
