57 \fBint\fR \fBt_sndrel\fR(\fBint\fR \fIfd\fR);
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 For transport providers of type \fBT_COTS_ORD,\fR this function is used to
73 initiate an orderly release of the outgoing direction of data transfer and
74 indicates to the transport provider that the transport user has no more data to
75 send. The argument \fIfd\fR identifies the local transport endpoint where the
76 connection exists. After calling \fBt_sndrel()\fR, the user may not send any
77 more data over the connection. However, a user may continue to receive data if
78 an orderly release indication has not been received. For transport providers of
79 types other than \fBT_COTS_ORD,\fR this function fails with error
84 Upon successful completion, a value of \fB0\fR is returned. Otherwise, a
85 value of -1 is \fBreturned\fR and \fBt_errno\fR is set to indicate an error.
89 \fBT_DATAXFER\fR, \fBT_INREL\fR.
93 On failure, \fBt_errno\fR is set to one of the following:
100 The specified file descriptor does not refer to a transport endpoint.
109 \fBO_NONBLOCK\fR was set, but the flow control mechanism prevented the
110 transport provider from accepting the function at this time.
119 An asynchronous event has occurred on this transport endpoint and requires
126 \fB\fBTNOTSUPPORT\fR\fR
129 This function is not supported by the underlying transport provider.
135 \fB\fBTOUTSTATE\fR\fR
138 The communications endpoint referenced by \fIfd\fR is not in one of the states
139 in which a call to this function is valid.
148 This error indicates that a communication problem has been detected between XTI
149 and the transport provider for which there is no other suitable XTI error
159 A system error has occurred during execution of this function.
162 .SH TLI COMPATIBILITY
165 The \fBXTI\fR and \fBTLI\fR interface definitions have common names but use
166 different header files. This, and other semantic differences between the two
167 interfaces are described in the subsections below.
168 .SS "Interface Header"
171 The \fBXTI\fR interfaces use the header file, \fBxti.h\fR. \fBTLI\fR interfaces
172 should \fInot\fR use this header. They should use the header:
177 .SS "Error Description Values"
180 The \fBt_errno\fR values that can be set by the \fBXTI\fR interface and cannot
181 be set by the \fBTLI\fR interface are:
197 Whenever this function fails with \fBt_error\fR set to \fBTFLOW,\fR
198 \fBO_NONBLOCK\fR must have been set.
