  • 项目

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

This callback function is only used with older DirectDraw interfaces. It is superseded by the EnumModesCallback2 function for the IDirectDraw4::EnumDisplayModes method.

Return Values

The callback function returns DDENUMRET_OK to continue the enumeration.
