NDIS_TAPI_SEND_USER_USER_INFO

  • Article

OID_TAPI_SEND_USER_USER_INFO uses the NDIS_TAPI_SEND_USER_USER_INFO structure when it requests the miniport driver to send user-to-user information to the remote party on the specified call.

Support for this request is optional.

typedef struct _NDIS_TAPI_SEND_USER_USER_INFO { 
  ULONG ulRequestID; 
  HDRV_CALL hdCall; 
  ULONG ulUserUserInfoSize; 
  UCHAR UserUserInfo[1]; 
} NDIS_TAPI_SEND_USER_USER_INFO, *PNDIS_TAPI_SEND_USER_USER_INFO;

  • hdCall
