LINEEXTENSIONID

The LINEEXTENSIONID structure describes an extension identifier. Extension IDs are used to identify service provider-specific extensions for line devices.

typedef struct lineextensionid_tag {
    DWORD  dwExtensionID0;
    DWORD  dwExtensionID1;
    DWORD  dwExtensionID2;
    DWORD  dwExtensionID3;
} LINEEXTENSIONID, FAR *LPLINEEXTENSIONID; 
 

Members

dwExtensionID0

dwExtensionID1

dwExtensionID2

dwExtensionID3

These four DWORD-sized members together specify a universally unique extension identifier that identifies a line device class extension.

Remarks

No extensions.

Extension identifiers are generated using an SDK-provided generation utility.
