.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 asymmetric manner,
.IR zmq_bind
should be called first,
.IR zmq_connect
afterwards. Formats of the
.IR addr
parameter are defined by individual transports. For a list of supported
transports have a look at
.IR zmq(7)
manual page.

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.
.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);
