NAME

6       nn_close - close an SP socket
7

SYNOPSIS

9       #include <nanomsg/nn.h>
10
11       int nn_close (int s);
12

DESCRIPTION

14       Closes the socket s. Any buffered inbound messages that were not yet
15       received by the application will be discarded. The library will try to
16       deliver any outstanding outbound messages for the time specified by
17       NN_LINGER socket option. The call will block in the meantime.
18

RETURN VALUE

20       If the function succeeds zero is returned. Otherwise, -1 is returned
21       and errno is set to to one of the values defined below.
22

ERRORS

24       EBADF
25           The provided socket is invalid.
26
27       EINTR
28           Operation was interrupted by a signal. The socket is not fully
29           closed yet. Operation can be re-started by calling nn_close()
30           again.
31

EXAMPLE

33           int s = nn_socket (AF_SP, NN_PUB);
34           assert (s >= 0);
35           int rc = nn_close (s);
36           assert (rc == 0);
