gnutls_bye(3)			    gnutls			 gnutls_bye(3)

NAME
       gnutls_bye - terminate the current TLS/SSL connection.

SYNOPSIS
       #include <gnutls/gnutls.h>

       int gnutls_bye(gnutls_session_t session, gnutls_close_request_t how);

ARGUMENTS
       gnutls_session_t session
		   is a gnutls_session_t structure.

       gnutls_close_request_t how
		   is an integer

DESCRIPTION
       Terminates  the	current TLS/SSL connection. The connection should have
       been  initiated	using  gnutls_handshake().   how  should  be  one   of
       GNUTLS_SHUT_RDWR, GNUTLS_SHUT_WR.

       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 connec‐
       tion.   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	recom‐
       mended.

       This  function  may also return GNUTLS_E_AGAIN or GNUTLS_E_INTERRUPTED;
       cf.  gnutls_record_get_direction().

RETURNS
       GNUTLS_E_SUCCESS on success, or an error code, see function  documenta‐
       tion for entire semantics.
