D3DENUMDEVICESCALLBACK is the prototype definition for the callback function to enumerate installed Direct3D devices.
typedef HRESULT (FAR PASCAL * LPD3DENUMDEVICESCALLBACK)
(LPGUID lpGuid,
LPSTR lpDeviceDescription,
LPSTR lpDeviceName,
LPD3DDEVICEDESC lpD3DHWDeviceDesc,
LPD3DDEVICEDESC lpD3DHELDeviceDesc,
LPVOID lpUserArg
);
Applications should return one of the following values:
D3DENUMRET_CANCEL | |
Cancel the enumeration. | |
D3DENUMRET_OK | |
Continue the enumeration. |
When determining the order in which to call callback functions, the system searches the objects highest in the hierarchy first, and then calls their callback functions in the order in which they were created.
