26 This routine is part of the \fBXTI\fR interfaces which evolved from the
27 \fBTLI\fR interfaces. \fBXTI\fR represents the future evolution of these
28 interfaces. However, \fBTLI\fR interfaces are supported for compatibility. When
29 using a \fBTLI\fR routine that has the same name as an \fBXTI\fR routine, the
30 \fBtiuser.h\fR header file must be used. Refer to the \fBTLI\fR
31 \fBCOMPATIBILITY\fR section for a description of differences between the two
35 The \fBt_getstate()\fR function returns the current state of the provider
36 associated with the transport endpoint specified by \fIfd\fR.
40 State is returned upon successful completion. Otherwise, a value of -1 is
41 returned and \fBt_errno\fR is set to indicate an error. The current state is
67 Outgoing connection pending.
76 Incoming connection pending.
82 \fB\fBT_DATAXFER\fR \fR
94 Outgoing direction orderly release sent.
103 Incoming direction orderly release received.
108 If the provider is undergoing a state transition when \fBt_getstate()\fR is
109 called, the function will fail.
113 On failure, \fBt_errno\fR is set to one of the following:
120 The specified file descriptor does not refer to a transport endpoint.
129 This error indicates that a communication problem has been detected between XTI
130 and the transport provider for which there is no other suitable XTI error
137 \fB\fBTSTATECHNG\fR\fR
140 The transport provider is undergoing a transient state change.
149 A system error has occurred during execution of this function.
152 .SH TLI COMPATIBILITY
155 The \fBXTI\fR and \fBTLI\fR interface definitions have common names but use
156 different header files. This, and other semantic differences between the two
157 interfaces are described in the subsections below.
158 .SS "Interface Header"
161 The \fBXTI\fR interfaces use the header file, \fBxti.h\fR. \fBTLI\fR interfaces
162 should \fInot\fR use this header. They should use the header:
170 .SS "Error Description Values"
173 The \fBt_errno\fR value that can be set by the \fBXTI\fR interface and cannot
174 be set by the \fBTLI\fR interface is:
