- nn_close(3)
- ===========
- NAME
- ----
- nn_close - close an SP socket
- SYNOPSIS
- --------
- *#include <nanomsg/nn.h>*
- *int nn_close (int 's');*
- DESCRIPTION
- -----------
- 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.
- RETURN VALUE
- ------------
- If the function succeeds zero is returned. Otherwise, -1 is
- returned and 'errno' is set to to one of the values defined below.
- ERRORS
- ------
- *EBADF*::
- The provided socket is invalid.
- *EINTR*::
- Operation was interrupted by a signal. The socket is not fully closed yet.
- Operation can be re-started by calling _nn_close()_ again.
- EXAMPLE
- -------
- ----
- int s = nn_socket (AF_SP, NN_PUB);
- assert (s >= 0);
- int rc = nn_close (s);
- assert (rc == 0);
