27 This function is used to initiate an orderly release of the outgoing direction
28 of data transfer and to send user data with the release. The argument
29 \fIfd\fR identifies the local transport endpoint where the connection exists,
30 and \fIdiscon\fR points to a \fB t_discon\fR structure containing the
43 After calling \fBt_sndreldata()\fR, the user may not send any more data over
44 the connection. However, a user may continue to receive data if an orderly
45 release indication has not been received.
48 The field \fIreason\fR specifies the reason for the disconnection through a
49 protocol-dependent \fIreason code\fR, and \fIudata\fR identifies any user
50 data that is sent with the disconnection; the field \fIsequence\fR is not
54 The \fIudata\fR structure specifies the user data to be sent to the remote
55 user. The amount of user data must not exceed the limits supported by the
56 transport provider, as returned in the \fIdiscon\fR field of the \fIinfo\fR
57 argument of \fBt_open\fR(3NSL) or \fBt_getinfo\fR(3NSL). If the \fIlen\fR
58 field of \fIudata\fR is zero or if the provider did not return
59 \fBT_ORDRELDATA\fR in the \fBt_open\fR(3NSL) flags, no data will be sent to
63 If a user does not wish to send data and reason code to the remote user, the
64 value of \fIdiscon\fR may be a null pointer.
67 This function is an optional service of the transport provider, only supported
68 by providers of service type \fBT_COTS_ORD.\fR The flag \fBT_ORDRELDATA\fR in
69 the \fIinfo\(->flag\fR field returned by \fBt_open\fR(3NSL) or

74 This function may not be available on all systems.
78 Upon successful completion, a value of \fB0\fR is returned. Otherwise, a
79 value of -1 is returned and \fBt_errno\fR is set to indicate an error.
83 \fBT_DATAXFER\fR, \fBT_INREL\fR.
87 On failure, \fBt_errno\fR is set to one of the following:
94 The amount of user data specified was not within the bounds allowed by the
95 transport provider, or user data was supplied and the provider did not return
96 \fBT_ORDRELDATA\fR in the \fBt_open\fR(3NSL) flags.
105 The specified file descriptor does not refer to a transport endpoint.
114 \fBO_NONBLOCK\fR was set, but the flow control mechanism prevented the
115 transport provider from accepting the function at this time.

134 Orderly release is not supported by the underlying transport provider.
140 \fB\fBTOUTSTATE\fR\fR
143 The communications endpoint referenced by \fIfd\fR is not in one of the states
144 in which a call to this function is valid.
153 This error indicates that a communication problem has been detected between XTI
154 and the transport provider for which there is no other suitable XTI error
164 A system error has occurred during execution of this function.

170 In the \fBTLI\fR interface definition, no counterpart of this routine was
175 See \fBattributes\fR(5) for descriptions of the following attributes:
183 ATTRIBUTE TYPE ATTRIBUTE VALUE
191 \fBt_getinfo\fR(3NSL), \fBt_open\fR(3NSL), \fBt_rcvrel\fR(3NSL),
192 \fBt_rcvreldata\fR(3NSL), \fBt_sndrel\fR(3NSL), \fBattributes\fR(5)
196 The interfaces \fBt_sndreldata()\fR and \fBt_rcvreldata\fR(3NSL) are only for
197 use with a specific transport called "minimal OSI," which is not available on
198 the Solaris platform. These interfaces are not available for use in conjunction
199 with Internet Transports (\fBTCP\fR or \fBUDP\fR).
