NAME¶
xs_connect - connect a socketSYNOPSIS¶
int xs_connect (void *socket, const char *endpoint );DESCRIPTION¶
The xs_connect() function shall connect the socket referenced by the socket argument to the endpoint specified by the endpoint 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: inproclocal 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_connect() function shall return endpoint ID if successful. Otherwise it shall return -1 and set errno to one of the values defined below.ERRORS¶
EINVALThe 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.
ETERM
The context associated with the specified
socket was terminated.
ENOTSOCK
The provided socket was invalid.
EXAMPLE¶
Connecting a subscriber socket to an in-process and a TCP transport./* Create a XS_SUB socket */ void *socket = xs_socket (context, XS_SUB); assert (socket); /* Connect it to an in-process transport with the address 'my_publisher' */ int rc = xs_connect (socket, "inproc://my_publisher"); assert (rc != -1); /* Connect it to the host server001, port 5555 using a TCP transport */ rc = xs_connect (socket, "tcp://server001:5555"); assert (rc != -1);
