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 \fBt_unbind()\fR function disables the transport endpoint specified by \fIfd\fR which was previously bound by \fBt_bind\fR(3NSL). On completion of this call, no further data or events destined for this transport endpoint will be accepted by the transport provider. An endpoint which is disabled by using \fBt_unbind()\fR can be enabled by a subsequent call to \fBt_bind\fR(3NSL). .SH RETURN VALUES .sp .LP 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 .sp .LP \fBT_IDLE\fR. .SH ERRORS .sp .LP On failure, \fBt_errno\fR is set to one of the following: .sp .ne 2 .na \fB\fBTBADF\fR\fR .ad .RS 13n The specified file descriptor does not refer to a transport endpoint. .RE .sp .ne 2 .na \fB\fBTLOOK\fR\fR .ad .RS 13n An asynchronous event has occurred on this transport endpoint. .RE .sp .ne 2 .na \fB\fBTOUTSTATE\fR\fR .ad .RS 13n 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 13n 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 13n A system error has occurred during execution of this function. .RE .SH TLI COMPATIBILITY .sp .LP 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" .sp .LP The \fBXTI\fR interfaces use the header file, \fBxti.h\fR \fB\&.\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" .sp .LP The \fBt_errno\fR value that can be set by the \fBXTI\fR interface and cannot be set by the \fBTLI\fR interface is: .br .in +2 \fBTPROTO\fR .in -2 .SH ATTRIBUTES .sp .LP See \fBattributes\fR(5) for descriptions of the following attributes: .sp .sp .TS box; c | c l | l .
