  • Article

3/26/2014

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 lineNegotiateAPIVersion function and the TSPI_lineGetExtensionID function.

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.
