NAME

6       gnutls_bye - API function
7

SYNOPSIS

9       #include <gnutls/gnutls.h>
10
11       int gnutls_bye(gnutls_session_t session, gnutls_close_request_t how);
12

ARGUMENTS

14       gnutls_session_t session
15                   is a gnutls_session_t type.
16
17       gnutls_close_request_t how
18                   is an integer
19

DESCRIPTION

21       Terminates  the  current TLS/SSL connection. The connection should have
22       been  initiated  using  gnutls_handshake().    how  should  be  one  of
23       GNUTLS_SHUT_RDWR, GNUTLS_SHUT_WR.
24
25       In case of GNUTLS_SHUT_RDWR the TLS session gets terminated and further
26       receives and sends will be disallowed.  If the return value is zero you
27       may  continue  using  the  underlying transport layer. GNUTLS_SHUT_RDWR
28       sends an alert containing a close request and waits  for  the  peer  to
29       reply with the same message.
30
31       In  case  of GNUTLS_SHUT_WR the TLS session gets terminated and further
32       sends will be disallowed. In order to reuse the connection  you  should
33       wait  for an EOF from the peer.  GNUTLS_SHUT_WR sends an alert contain‐
34       ing a close request.
35
36       Note that not all implementations will properly terminate a TLS connec‐
37       tion.   Some  of  them, usually for performance reasons, will terminate
38       only the  underlying  transport  layer,  and  thus  not  distinguishing
39       between  a  malicious  party prematurely terminating the connection and
40       normal termination.
41
42       This function may also return GNUTLS_E_AGAIN  or  GNUTLS_E_INTERRUPTED;
43       cf.  gnutls_record_get_direction().
44

RETURNS

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