DIPROPGUIDANDPATH

The DIPROPGUIDANDPATH structure is used to access properties whose values represent a GUID and a path.

typedef struct {
    DIPROPHEADER diph;
    GUID         guidClass;
    WCHAR        wszPath[MAX_PATH];
} DIPROPGUIDANDPATH, *LPDIPROPGUIDANDPATH;

Members

diph

A DIPROPHEADER structure that must be initialized as follows:

dwSize	sizeof(DIPROPGUIDANDPATH)
dwHeaderSize	sizeof(DIPROPHEADER)
dwObj	Identifier of the object. For devices, must be zero
dwHow	How the dwObj member should be interpreted.

guidClass

The class GUID for the object.

wszPath

The returned path for the object. This is a Unicode string.

Remarks

The DIPROP_GUIDANDPATH property associated with the DIPROPGUIDANDPATH structure allows advanced applications to perform operations on the device that are not supported by DirectInput.

The application calls the IDirectInputDevice::GetProperty method with DIPROP_GUIDANDPATH as the rguidProp parameter. The class GUID of the device is returned in the guidClass member of the DIPROPGUIDANDPATH structure, and the device interface path is returned in the wszPath member. The application can then call the CreateFile function on this path in order to access the device directly.

Most applications should have no need for this property structure.
