== NAME
nn_shutdown - shut down endpoint (compatible API)
== SYNOPSIS
[source, c]
----
#include <nanomsg/nn.h>
int nn_shutdown(int sock, int ep)
----
== DESCRIPTION
The `nn_shutdown()` shuts down the "`endpoint`" _ep_ on the socket _sock_.
This will stop the socket from either accepting new connections, or establishing
old ones.
Additionally, any established connections associated with _ep_ will be
closed.
NOTE: This function is provided for API
<<nng_compat.3compat#,compatibility>> with legacy _libnanomsg_.
Consider using the relevant <<libnng.3#,modern API>> instead.
== RETURN VALUES
This function returns zero on success, and -1 on error.
== ERRORS
[horizontal]
`EBADF`:: The socket _sock_ is not open.
`EINVAL`:: An invalid _ep_ was supplied.
