6 zmq_bind - accept connections on a socket
7
9 int zmq_bind (void *socket, const char *endpoint);
10
12 The zmq_bind() function shall create an endpoint for accepting
13 connections and bind it to the socket referenced by the socket
14 argument.
15
16 The endpoint argument is a string consisting of two parts as follows:
17 transport://address. The transport part specifies the underlying
18 transport protocol to use. The meaning of the address part is specific
19 to the underlying transport protocol selected.
20
21 The following transports are defined:
22
23 inproc
24 local in-process (inter-thread) communication transport, see
25 zmq_inproc(7)
26
27 ipc
28 local inter-process communication transport, see zmq_ipc(7)
29
30 tcp
31 unicast transport using TCP, see zmq_tcp(7)
32
33 pgm, epgm
34 reliable multicast transport using PGM, see zmq_pgm(7)
35
36 With the exception of ZMQ_PAIR sockets, a single socket may be
37 connected to multiple endpoints using zmq_connect(), while
38 simultaneously accepting incoming connections from multiple endpoints
39 bound to the socket using zmq_bind(). Refer to zmq_socket(3) for a
40 description of the exact semantics involved when connecting or binding
41 a socket to multiple endpoints.
42
44 The zmq_bind() function shall return zero if successful. Otherwise it
45 shall return -1 and set errno to one of the values defined below.
46
48 EPROTONOSUPPORT
49 The requested transport protocol is not supported.
50
51 ENOCOMPATPROTO
52 The requested transport protocol is not compatible with the socket
53 type.
54
55 EADDRINUSE
56 The requested address is already in use.
57
58 EADDRNOTAVAIL
59 The requested address was not local.
60
61 ENODEV
62 The requested address specifies a nonexistent interface.
63
64 ETERM
65 The 0MQ context associated with the specified socket was
66 terminated.
67
68 EFAULT
69 The provided socket was not valid (NULL).
70
71 EMTHREAD
72 No I/O thread is available to accomplish the task.
73
75 Binding a publisher socket to an in-process and a TCP transport.
76
77 /* Create a ZMQ_PUB socket */
78 void *socket = zmq_socket (context, ZMQ_PUB);
79 assert (socket);
80 /* Bind it to a in-process transport with the address 'my_publisher' */
81 int rc = zmq_bind (socket, "inproc://my_publisher");
82 assert (rc == 0);
83 /* Bind it to a TCP transport on port 5555 of the 'eth0' interface */
84 rc = zmq_bind (socket, "tcp://eth0:5555");
85 assert (rc == 0);
