.SH "NAME"
zmq_ctx_destroy \- terminate a 0MQ context
.SH "SYNOPSIS"
.sp
\fBint zmq_ctx_destroy (void \fR\fB\fI*context\fR\fR\fB);\fR
.SH "DESCRIPTION"
.sp
The \fIzmq_ctx_destroy()\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
.RS 4
.ie n \{\
\h'-04' 2.\h'+01'\c
.\}
.el \{\
.sp -1
.IP " 2." 4.2
.\}
After interrupting all blocking calls,
\fIzmq_ctx_destroy()\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
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.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 is deprecated by \fBzmq_ctx_term\fR(3)\&.
.SH "RETURN VALUE"
.sp
The \fIzmq_ctx_destroy()\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
\fIcontext\fR
was invalid\&.
.RE
.PP
\fBEINTR\fR
.RS 4
Termination was interrupted by a signal\&. It can be restarted if needed\&.
.RE
