NN_CLOSE(3) nanomsg 1.1.5 NN_CLOSE(3)

nn_close - close an SP socket

#include <nanomsg/nn.h>
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 errno is set to to one of the values defined below.

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.

int s = nn_socket (AF_SP, NN_PUB);
assert (s >= 0);
int rc = nn_close (s);
assert (rc == 0);
