NAME¶

xs_bind - accept connections on a socket

SYNOPSIS¶

int xs_bind (void *socket, const char *endpoint);

DESCRIPTION¶

The xs_bind() function shall create an endpoint for accepting connections and bind it to the socket referenced by the socket argument.

The endpoint argument is a string consisting of two parts as follows: transport://address. The transport part specifies the underlying transport protocol to use. The meaning of the address part is specific to the underlying transport protocol selected.

The following transports are defined:

inproc

ipc

tcp

pgm, epgm

With the exception of XS_PAIR sockets, a single socket may be connected to multiple endpoints using xs_connect(), while simultaneously accepting incoming connections from multiple endpoints bound to the socket using xs_bind(). Refer to xs_socket(3) for a description of the exact semantics involved when connecting or binding a socket to multiple endpoints.

RETURN VALUE¶

The xs_bind() function shall return endpoint ID if successful. Otherwise it shall return -1 and set errno to one of the values defined below.

ERRORS¶

EINVAL

ENAMETOOLONG

EPROTONOSUPPORT

ENOCOMPATPROTO

EADDRINUSE

EADDRNOTAVAIL

ENODEV

ETERM

ENOTSOCK

EXAMPLE¶

Binding a publisher socket to an in-process and a TCP transport.

/* Create a XS_PUB socket */
void *socket = xs_socket (context, XS_PUB);
assert (socket);
/* Bind it to a in-process transport with the address 'my_publisher' */
int rc = xs_bind (socket, "inproc://my_publisher");
assert (rc != -1);
/* Bind it to a TCP transport on port 5555 of the 'eth0' interface */
rc = xs_bind (socket, "tcp://eth0:5555");
assert (rc != -1);
