xs_shutdown3

Usage

Overview

This function partially closes the socket. It disconnects or unbinds an endpoint previously connected or bound by xs_bind() or xs_connect(). how parameter is the endpoint ID as returned by xs_bind() or xs_connect().

Endpoint shutdown honours linger socket option. I.e. if there are any pending outbound messages, Crossroads will try to push them to the network for the specified amount of time before giving up.

Note: inproc endpoints don’t support partial shutdown at the moment.

Return value

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

Errors

EINVAL

ENOTSUP

ETERM

ENOTSOCK

Examples

Binding socket to an endpoint, then unbinding it.

/* Create a socket */
void *socket = xs_socket (context, XS_PUB);
assert (socket);
/* Bind it to a TCP endpoint */
int id = xs_bind (socket, "tcp://*:5555");
assert (id != -1);
/* Unbind the socket from the endpoint */
rc = xs_shutdown (socket, id);
assert (rc == 0);
