NAME
gnutls_bye - API function
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 type.
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 the TLS session gets terminated and further
receives and sends will be disallowed. If the return value is zero you
may continue using the underlying transport layer. GNUTLS_SHUT_RDWR
sends an alert containing a close request and waits for the peer to
reply with the same message.
In case of GNUTLS_SHUT_WR the TLS session 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, and thus not
distinguishing between a malicious party prematurely terminating the
connection and normal termination.
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
documentation for entire semantics.
