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 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.
