However, \fBTLI\fR interfaces are supported for compatibility. When using a \fBTLI\fR routine that has the same name as an \fBXTI\fR routine, the \fBtiuser.h\fR header file must be used. Refer to the \fBTLI\fR \fBCOMPATIBILITY\fR section for a description of differences between the two interfaces. .sp .LP This function is used to receive an orderly release indication for the incoming direction of data transfer. The argument \fIfd\fR identifies the local transport endpoint where the connection exists. After receipt of this indication, the user may not attempt to receive more data by means of \fBt_rcv\fR(3NSL) or \fBt_rcvv()\fR. Such an attempt will fail with \fIt_error\fR set to \fBTOUTSTATE\fR. However, the user may continue to send data over the connection if \fBt_sndrel\fR(3NSL) has not been called by the user. This function is an optional service of the transport provider, and is only supported if the transport provider returned service type \fBT_COTS_ORD\fR on \fBt_open\fR(3NSL) or \fBt_getinfo\fR(3NSL). Any user data that may be associated with the orderly release indication is discarded when \fBt_rcvrel()\fR is called. .SH RETURN VALUES Upon successful completion, a value of \fB0\fR is returned. Otherwise, a value of -1 is returned and \fBt_errno\fR is set to indicate an error. .SH VALID STATES \fBT_DATAXFER\fR, \fBT_OUTREL\fR. .SH ERRORS On failure, \fBt_errno\fR is set to one of the following: .sp .ne 2 .na \fB\fBTBADF\fR\fR .ad .RS 15n The specified file descriptor does not refer to a transport endpoint. .RE .sp .ne 2 .na \fB\fBTLOOK\fR\fR .ad .RS 15n An asynchronous event has occurred on this transport endpoint and requires immediate attention. .RE .sp .ne 2 .na \fB\fBTNOREL\fR\fR .ad .RS 15n No orderly release indication currently exists on the specified transport endpoint. .RE .sp .ne 2 .na \fB\fBTNOTSUPPORT\fR\fR .ad .RS 15n This function is not supported by the underlying transport provider. .RE .sp .ne 2 .na \fB\fBTOUTSTATE\fR\fR .ad .RS 15n The communications endpoint referenced by \fIfd\fR is not in one of the states in which a call to this function is valid. .RE .sp .ne 2 .na \fB\fBTPROTO\fR\fR .ad .RS 15n This error indicates that a communication problem has been detected between XTI and the transport provider for which there is no other suitable XTI error \fB(t_errno)\fR. .RE .sp .ne 2 .na \fB\fBTSYSERR\fR\fR .ad .RS 15n A system error has occurred during execution of this function. .RE .SH TLI COMPATIBILITY The \fBXTI\fR and \fBTLI\fR interface definitions have common names but use different header files. This, and other semantic differences between the two interfaces are described in the subsections below. .SS "Interface Header" The \fBXTI\fR interfaces use the header file, \fBxti.h\fR. \fBTLI\fR interfaces should \fInot\fR use this header. They should use the header: .br .in +2 #include .in -2 .SS "Error Description Values" The \fBt_errno\fR values that can be set by the \fBXTI\fR interface and cannot be set by the \fBTLI\fR interface are: .br .in +2 \fBTPROTO\fR .in -2 .br .in +2 \fBTOUTSTATE\fR .in -2 .SH ATTRIBUTES See \fBattributes\fR(7) for descriptions of the following attributes: .sp .sp .TS box; c | c l | l .
