+.SH "NAME"
+zmq_ctx_destroy \- destroy 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\&.

+.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\&.

+.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 replaces the deprecated function \fBzmq_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\&.

+\fBEINTR\fR
+.RS 4
+Termination was interrupted by a signal\&. It can be restarted if needed\&.
