OID_TAPI_SEND_USER_USER_INFO
The OID_TAPI_SEND_USER_INFO OID requests the miniport driver to send user-to-user information to the remote party on the specified call.
Support for this request is optional.
This request uses an NDIS_TAPI_SEND_USER_USER_INFO structure, defined as follows:
typedef struct _NDIS_TAPI_SEND_USER_USER_INFO {
IN ULONG ulRequestID;
IN HDRV_CALL hdCall;
IN ULONG ulUserUserInfoSize;
IN UCHAR UserUserInfo[1];
} NDIS_TAPI_SEND_USER_USER_INFO, *PNDIS_TAPI_SEND_USER_USER_INFO;
The members of this structure contain the following information:
ulRequestID
Reserved.hdCall
Specifies the miniport driver's handle to the call on which to send user-to-user information.ulUserUserInfoSize
Specifies the size in bytes of the UserUserInfo string.UserUserInfo
Specifies a string containing user-to-user information to be sent to the remote party as part of a call-accept operation. User-to-user information is sent only if supported by the underlying network (see OID_TAPI_GET_DEV_CAPS).
The MiniportSetInformationfunction can return one of the following:
NDIS_STATUS_SUCCESS
NDIS_STATUS_PENDING
NDIS_STATUS_TAPI_INVALCALLHANDLE
NDIS_STATUS_TAPI_INVALCALLSTATE
NDIS_STATUS_TAPI_USERUSERINFOTOOBIG
NDIS_STATUS_TAPI_OPERATIONUNAVAIL
NDIS_STATUS_TAPI_RESOURCEUNAVAIL
NDIS_STATUS_FAILURE
