This structure describes an extension identifier. Extension identifiers are used to identify service provider-specific extensions for line devices. Multiple functions use this structure, including the lineNegotiateAPIVersionfunction and the TSPI_lineGetExtensionIDfunction.

Syntax 

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

Members

dwExtensionID0

First part of the extension identifier.

dwExtensionID1

Second part of the extension identifier.

dwExtensionID2

Third part of the extension identifier.

dwExtensionID3

Fourth part of the extension identifier.

Remarks

These four members together specify a universally unique extension identifier that identifies a line device class extension. This structure may not be extended.
