XS_BIND(3) Crossroads I/O Manual XS_BIND(3)NAMExs_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
local in-process (inter-thread) communication transport, see
xs_inproc(7)
ipc
local inter-process communication transport, see xs_ipc(7)
tcp
unicast transport using TCP, see xs_tcp(7)
pgm, epgm
reliable multicast transport using PGM, see xs_pgm(7)
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
The endpoint supplied is invalid.
ENAMETOOLONG
The supplied name was too long.
EPROTONOSUPPORT
The requested transport protocol is not supported.
ENOCOMPATPROTO
The requested transport protocol is not compatible with the socket
type.
EADDRINUSE
The requested address is already in use.
EADDRNOTAVAIL
The requested address was not local.
ENODEV
The requested address specifies a nonexistent interface.
ETERM
The context associated with the specified socket was terminated.
ENOTSOCK
The provided socket was invalid.
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);
