zmq_unbind \- Stop accepting connections on a socket
|
|
.SH "SYNOPSIS"
|
|
.sp
|
|
int zmq_unbind (void \fI*socket\fR, const char \fI*endpoint\fR);
|
|
.SH "DESCRIPTION"
|
|
.sp
|
|
The \fIzmq_unbind()\fR function shall unbind a socket specified by the \fIsocket\fR argument from the endpoint specified by the \fIendpoint\fR argument\&.
|
|
.sp
|
|
The \fIendpoint\fR argument is as described in \fBzmq_bind\fR(3)
|
|
.SS "Unbinding wild\-card addres from a socket"
|
|
.sp
|
|
When wild\-card * \fIendpoint\fR (described in \fBzmq_tcp\fR(7) and \fBzmq_ipc\fR(7)) was used in \fIzmq_bind()\fR, the caller should use real \fIendpoind\fR obtained from the ZMQ_LAST_ENDPOINT socket option to unbind this \fIendpoint\fR from a socket\&.
|
|
.SH "RETURN VALUE"
|
|
.sp
|
|
The \fIzmq_unbind()\fR function shall return zero if successful\&. Otherwise it shall return \-1 and set \fIerrno\fR to one of the values defined below\&.
