# libssh2\_session\_disconnect\_ex(3)

terminate transport layer

## NAME

libssh2\_session\_disconnect\_ex - terminate transport layer

## SYNOPSIS

```
#include <libssh2.h>
int
libssh2_session_disconnect_ex(LIBSSH2_SESSION *session, int reason,
                              const char *description,
                              const char *lang);
int
libssh2_session_disconnect(LIBSSH2_SESSION *session,
                           const char *description);
```

## DESCRIPTION

*session* - Session instance as returned by **[libssh2\_session\_init\_ex(3)](/libssh2_session_init_ex/3.md)**

*reason* - One of the Disconnect Reason constants.

*description* - Human readable reason for disconnection.

*lang* - Localization string describing the language/encoding of the description provided.

Send a disconnect message to the remote host associated with *session*, along with a *reason* symbol and a verbose *description*.

As a convenience, the macro **[libssh2\_session\_disconnect(3)](/libssh2_session_disconnect/3.md)** is provided. It calls **[libssh2\_session\_disconnect\_ex(3)](/libssh2_session_disconnect_ex/3.md)** with *reason* set to SSH\_DISCONNECT\_BY\_APPLICATION and *lang* set to an empty string.

## RETURN VALUE

Return 0 on success or negative on failure. It returns LIBSSH2\_ERROR\_EAGAIN when it would otherwise block. While LIBSSH2\_ERROR\_EAGAIN is a negative number, it is not really a failure per se.
