nn_close - close an SP socket
int nn_close (int s);
Closes the socket s
. Any buffered inbound messages that were not yet
received by the application will be discarded. The library will try to deliver
any outstanding outbound messages for the time specified by NN_LINGER
socket option. The call will block in the meantime.
If the function succeeds zero is returned. Otherwise, -1 is returned and
is set to to one of the values defined below.
The provided socket is invalid.
Operation was interrupted by a signal. The socket is not
fully closed yet. Operation can be re-started by calling nn_close()
int s = nn_socket (AF_SP, NN_PUB);
assert (s >= 0);
int rc = nn_close (s);
assert (rc == 0);
