63 This routine is part of the \fBXTI\fR interfaces which evolved from the
64 \fBTLI\fR interfaces. \fBXTI\fR represents the future evolution of these
65 interfaces. However, \fBTLI\fR interfaces are supported for compatibility. When
66 using a \fBTLI\fR routine that has the same name as an \fBXTI\fR routine, the
67 \fBtiuser.h\fR header file must be used. Refer to the \fBTLI\fR
68 \fBCOMPATIBILITY\fR section for a description of differences between the two
72 The \fBt_getstate()\fR function returns the current state of the provider
73 associated with the transport endpoint specified by \fIfd\fR.
77 State is returned upon successful completion. Otherwise, a value of -1 is
78 returned and \fBt_errno\fR is set to indicate an error. The current state is
101 \fB\fBT_OUTCON\fR \fR
104 Outgoing connection pending.
113 Incoming connection pending.

131 Outgoing direction orderly release sent.
140 Incoming direction orderly release received.
145 If the provider is undergoing a state transition when \fBt_getstate()\fR is
146 called, the function will fail.
150 On failure, \fBt_errno\fR is set to one of the following:
157 The specified file descriptor does not refer to a transport endpoint.
166 This error indicates that a communication problem has been detected between XTI
167 and the transport provider for which there is no other suitable XTI error
174 \fB\fBTSTATECHNG\fR\fR
177 The transport provider is undergoing a transient state change.
186 A system error has occurred during execution of this function.
189 .SH TLI COMPATIBILITY
192 The \fBXTI\fR and \fBTLI\fR interface definitions have common names but use
193 different header files. This, and other semantic differences between the two
194 interfaces are described in the subsections below.
195 .SS "Interface Header"
198 The \fBXTI\fR interfaces use the header file, \fBxti.h\fR. \fBTLI\fR interfaces
199 should \fInot\fR use this header. They should use the header:
207 .SS "Error Description Values"
210 The \fBt_errno\fR value that can be set by the \fBXTI\fR interface and cannot
211 be set by the \fBTLI\fR interface is:
