| =========== |

| 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); |
