  • [アーティクル]

3/26/2014

This structure describes an extension identifier. Extension identifiers are used to identify service provider-specific extensions for phone device classes. The phoneNegotiateAPIVersion and TSPI_phoneGetExtensionID functions return this structure.

Syntax

typedef struct phoneextensionid_tag {
  DWORD dwExtensionID0;
  DWORD dwExtensionID1;
  DWORD dwExtensionID2;
  DWORD dwExtensionID3;
} PHONEEXTENSIONID, FAR* LPPHONEEXTENSIONID;

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 phone device class extension. This structure may not be extended.
