\fBint zmq_ctx_term (void \fR\fB\fI*context\fR\fR\fB);\fR

.SH "DESCRIPTION"
|
|
.sp
|
|
The \fIzmq_ctx_term()\fR function shall destroy the 0MQ context \fIcontext\fR\&.
|
|
.sp
|
|
Context termination is performed in the following steps:
|
|
.sp
|
|
.RS 4
|
|
.ie n \{\
|
|
\h'-04' 1.\h'+01'\c
|
|
.\}
|
|
.el \{\
|
|
.sp -1
|
|
.IP " 1." 4.2
|
|
.\}
|
|
Any blocking operations currently in progress on sockets open within
|
|
\fIcontext\fR
|
|
shall return immediately with an error code of ETERM\&. With the exception of
|
|
\fIzmq_close()\fR, any further operations on sockets open within
|
|
\fIcontext\fR
|
|
shall fail with an error code of ETERM\&.
|
|
.RE
|

.sp
|

|
.\}
|
|
.el \{\
|
|
.sp -1
|
|
.IP " 2." 4.2
|
|
.\}
|
|
After interrupting all blocking calls,
|
|
\fIzmq_ctx_term()\fR
|
|
shall
|
|
\fIblock\fR
|
|
until the following conditions are satisfied:
|
|
.sp
|
|
.RS 4
|
|
.ie n \{\
|
|
\h'-04'\(bu\h'+03'\c
|
|
.\}
|
|
.el \{\
|
|
.sp -1
|
|
.IP \(bu 2.3
|
|
.\}
|
|
All sockets open within
|
|
\fIcontext\fR
|
|
have been closed with
|
|
\fIzmq_close()\fR\&.
|
|
.RE
|
|
.sp
|

.RS 4

|

.sp -1
|

.IP \(bu 2.3
|

.\}
|
|
For each socket within
|
|
\fIcontext\fR, all messages sent by the application with
|
|
\fIzmq_send()\fR
|
|
have either been physically transferred to a network peer, or the socket\(cqs linger period set with the
|
|
\fIZMQ_LINGER\fR
|
|
socket option has expired\&.
|
|
.RE
|
|
.RE
|
|
.sp
|
|
For further details regarding socket linger behavior refer to the \fIZMQ_LINGER\fR option in \fBzmq_setsockopt\fR(3)\&.
|
|
.sp
|
|
This function replaces the deprecated function \fBzmq_term\fR(3)\&.
|
|
.SH "WARNING"
|
|
.sp
|
|
As \fIZMQ_LINGER\fR defaults to "infinite", by default this function will block indefinitely if there are any pending connects or sends\&. We strongly recommend to (a) set \fIZMQ_LINGER\fR to zero on all sockets and (b) close all sockets, before calling this function\&.
|
|
.SH "RETURN VALUE"
|
|
.sp
|
|
The \fIzmq_ctx_term()\fR function shall return zero if successful\&. Otherwise it shall return \-1 and set \fIerrno\fR to one of the values defined below\&.
|
|
.SH "ERRORS"
|
|
.PP
|

\fBEFAULT\fR
|

.RS 4

The provided
