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

| NAME |
| ---- |
| nn_shutdown - remove an endpoint from a socket |
| |
| |
| SYNOPSIS |
| -------- |
| *#include <nanomsg/nn.h>* |
| |
| *int nn_shutdown (int 's', int 'how');* |
| |
| |
| DESCRIPTION |
| ----------- |
| Removes an endpoint from socket 's'. 'how' parameter specifies the ID of the |
| endpoint to remove as returned by prior call to linknanomsg:nn_bind[3] or |
| linknanomsg:nn_connect[3]. _nn_shutdown()_ call will return immediately, |
| however, the library will try to deliver any outstanding outbound messages to |
| the endpoint for the time specified by _NN_LINGER_ socket option. |
| |
| |
| RETURN VALUE |
| ------------ |
| If the function succeeds zero is returned. Otherwise, negative number is |
| returned and 'errno' is set to to one of the values defined below. |
| |
| |
| ERRORS |
| ------ |
| *EBADF*:: |
| The provided socket is invalid. |
| *EINVAL*:: |
| The 'how' parameter doesn't correspond to an active endpoint. |
| *EINTR*:: |
| Operation was interrupted by a signal. The endpoint is not fully closed yet. |
| Operation can be re-started by calling _nn_shutdown()_ again. |
| *ETERM*:: |
| The library is terminating. |
