NAME¶
zmq_connect - create outgoing connection from socketSYNOPSIS¶
int zmq_connect (void *socket, const char *endpoint );DESCRIPTION¶
The zmq_connect() function connects the socket to an endpoint and then accepts incoming connections on that endpoint. The endpoint is a string consisting of a transport:// followed by an address. The transport specifies the underlying protocol to use. The address specifies the transport-specific address to connect to. 0MQ provides the the following transports: tcpunicast transport using TCP, see zmq_tcp(7)
ipc
local inter-process communication transport, see
zmq_ipc(7)
inproc
local in-process (inter-thread) communication transport,
see zmq_inproc(7)
pgm, epgm
reliable multicast transport using PGM, see
zmq_pgm(7)
Every 0MQ socket type except ZMQ_PAIR supports one-to-many and
many-to-one semantics. The precise semantics depend on the socket type and are
defined in zmq_socket(3).
RETURN VALUE¶
The zmq_connect() function returns zero if successful. Otherwise it returns -1 and sets errno to one of the values defined below.ERRORS¶
EINVALThe endpoint supplied is invalid.
EPROTONOSUPPORT
The requested transport protocol is not
supported.
ENOCOMPATPROTO
The requested transport protocol is not compatible
with the socket type.
ETERM
The 0MQ context associated with the specified
socket was terminated.
ENOTSOCK
The provided socket was invalid.
EMTHREAD
No I/O thread is available to accomplish the task.
EXAMPLE¶
Connecting a subscriber socket to an in-process and a TCP transport./* Create a ZMQ_SUB socket */ void *socket = zmq_socket (context, ZMQ_SUB); assert (socket); /* Connect it to an in-process transport with the address 'my_publisher' */ int rc = zmq_connect (socket, "inproc://my_publisher"); assert (rc == 0); /* Connect it to the host server001, port 5555 using a TCP transport */ rc = zmq_connect (socket, "tcp://server001:5555"); assert (rc == 0);
