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 The \fBt_getstate()\fR function returns the current state of the provider associated with the transport endpoint specified by \fIfd\fR. .SH RETURN VALUES .sp .LP State is returned upon successful completion. Otherwise, a value of -1 is returned and \fBt_errno\fR is set to indicate an error. The current state is one of the following: .sp .ne 2 .na \fB\fBT_UNBND\fR \fR .ad .RS 15n Unbound. .RE .sp .ne 2 .na \fB\fBT_IDLE\fR \fR .ad .RS 15n Idle. .RE .sp .ne 2 .na \fB\fBT_OUTCON\fR \fR .ad .RS 15n Outgoing connection pending. .RE .sp .ne 2 .na \fB\fBT_INCON\fR \fR .ad .RS 15n Incoming connection pending. .RE .sp .ne 2 .na \fB\fBT_DATAXFER\fR \fR .ad .RS 15n Data transfer. .RE .sp .ne 2 .na \fB\fBT_OUTREL\fR \fR .ad .RS 15n Outgoing direction orderly release sent. .RE .sp .ne 2 .na \fB\fBT_INREL\fR \fR .ad .RS 15n Incoming direction orderly release received. .RE .sp .LP If the provider is undergoing a state transition when \fBt_getstate()\fR is called, the function will fail. .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 14n The specified file descriptor does not refer to a transport endpoint. .RE .sp .ne 2 .na \fB\fBTPROTO\fR\fR .ad .RS 14n 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\fBTSTATECHNG\fR\fR .ad .RS 14n The transport provider is undergoing a transient state change. .RE .sp .ne 2 .na \fB\fBTSYSERR\fR\fR .ad .RS 14n 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. \fBTLI\fR interfaces should \fInot\fR use this header. They should use the header: .sp .in +2 .nf #include .fi .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: .sp .LP \fBTPROTO\fR .SH ATTRIBUTES .sp .LP See \fBattributes\fR(5) for descriptions of the following attributes: .sp .sp .TS box; c | c l | l .
