EnumModesCallback

The EnumModesCallback function is an application-defined callback function for the IDirectDraw3::EnumDisplayModes method and its counterparts in earlier interfaces.

This callback function is superseded by the EnumModesCallback2 function that is used with the IDirectDraw7::EnumDisplayModes method.

HRESULT WINAPI EnumModesCallback(
  LPDDSURFACEDESC lpDDSurfaceDesc,  
  LPVOID lpContext                  
);

Parameters

lpDDSurfaceDesc: Address of a read-only DDSURFACEDESC structure that provides the monitor frequency and the mode that can be created.
lpContext: Address of an application-defined structure to be passed to the callback function each time that the function is called.

Return Values

The callback function returns DDENUMRET_OK to continue the enumeration.

It returns DDENUMRET_CANCEL to stop the enumeration.

Remarks

You can use the LPDDENUMMODESCALLBACK data type to declare a variable that can contain a pointer to this callback function.
