gnutls_bye - terminate the current TLS/SSL connection.
int gnutls_bye(gnutls_session_t session, gnutls_close_request_t how);
is a gnutls_session_t structure.

Terminates the current TLS/SSL connection. The connection should have
been initiated using gnutls_handshake(). how should be one of
In case of GNUTLS_SHUT_RDWR then the TLS connection gets terminated and
further receives and sends will be disallowed. If the return value is
zero you may continue using the connection. GNUTLS_SHUT_RDWR actually
sends an alert containing a close request and waits for the peer to
reply with the same message.
In case of GNUTLS_SHUT_WR then the TLS connection gets terminated and
further sends will be disallowed. In order to reuse the connection you
should wait for an EOF from the peer. GNUTLS_SHUT_WR sends an alert
containing a close request.
Note that not all implementations will properly terminate a TLS
connection. Some of them, usually for performance reasons, will
terminate only the underlying transport layer, thus causing a
transmission error to the peer. This error cannot be distinguished
from a malicious party prematurely terminating the session, thus this
behavior is not recommended.
This function may also return GNUTLS_E_AGAIN or GNUTLS_E_INTERRUPTED;
GNUTLS_E_SUCCESS on success, or an error code, see function
documentation for entire semantics.
