.TH zmq_connect 3 "" "(c)2007-2010 iMatix Corporation" "0MQ User Manuals"
.SH NAME
zmq_connect \- connect the socket to the specified peer
.SH SYNOPSIS
.B int zmq_connect (void *s, const char *addr);
.SH DESCRIPTION
The function connect socket
.IR s to the peer identified by
.IR addr .
Actual semantics of the command depend on the underlying transport mechanism,
however, in cases where peers connect in an asymetric manner,
.IR zmq_bind
should be called first,
.IR zmq_connect
afterwards. For actual formats of
.IR addr
parameter for different types of transport have a look at
.IR zmq(7) .
Note that single socket can be connected (and bound) to
arbitrary number of peers using different transport mechanisms.
.SH RETURN VALUE
In case of success the function returns zero. Otherwise it returns -1 and
sets
.IR errno
to the appropriate value.
.SH ERRORS
.IP "\fBEPROTONOSUPPORT\fP"
unsupported protocol.
.IP "\fBENOCOMPATPROTO\fP"
protocol is not compatible with the socket type.
.IP "\fBECONNREFUSED\fP"
no-one listening on the remote address.
.SH EXAMPLE
.nf
void *s = zmq_socket (context, ZMQ_SUB);
assert (s);
int rc = zmq_connect (s, "inproc://my_publisher");
assert (rc == 0);
rc = zmq_connect (s, "tcp://server001:5555");
assert (rc == 0);
