.SH "DESCRIPTION"

|
.sp
|
||
|
|
The \fIzmq_close()\fR function shall destroy the socket referenced by the \fIsocket\fR argument\&. Any outstanding messages physically received from the network but not yet received by the application with \fIzmq_recv()\fR shall be discarded\&. The behaviour for discarding messages sent by the application with \fIzmq_send()\fR but not yet physically transferred to the network depends on the value of the \fIZMQ_LINGER\fR socket option for the specified \fIsocket\fR\&.

The default setting of \fIZMQ_LINGER\fR does not discard unsent messages; this behaviour may cause the application to block when calling \fIzmq_ctx_term()\fR\&. For details refer to \fBzmq_setsockopt\fR(3) and \fBzmq_ctx_term\fR(3)\&.
