NAME
gnutls_bye - This function terminates 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().
