SSLsetshutdown(3) OpenSSL SSLsetshutdown(3)

NAME
       SSLsetshutdown, SSLgetshutdown - manipulate shutdown state of an
       SSL connection

SYNOPSIS
        #include 

        void SSLsetshutdown(SSL *ssl, int mode);

        int SSLgetshutdown(const SSL *ssl);

DESCRIPTION
       SSLsetshutdown() sets the shutdown state of ssssll to mmooddee.

       SSLgetshutdown() returns the shutdown mode of ssssll.

NNOOTTEESS
       The shutdown state of an ssl connection is a bitmask of:

       0   No shutdown setting, yet.

       SSLSENTSHUTDOWN
           A "close notify" shutdown alert was sent to the peer, the
           connection is being considered closed and the session is closed and
           correct.

       SSLRECEIVEDSHUTDOWN
           A shutdown alert was received form the peer, either a normal "close
           notify" or a fatal error.

       SSLSENTSHUTDOWN and SSLRECEIVEDSHUTDOWN can be set at the same
       time.

       The shutdown state of the connection is used to determine the state of
       the ssl session. If the session is still open, when SSLclear(3) or
       SSLfree(3) is called, it is considered bad and removed according to
       RFC2246.  The actual condition for a correctly closed session is
       SSLSENTSHUTDOWN (according to the TLS RFC, it is acceptable to only
       send the "close notify" alert but to not wait for the peer's answer,
       when the underlying connection is closed).  SSLsetshutdown() can be
       used to set this state without sending a close alert to the peer (see
       SSLshutdown(3)).

       If a "close notify" was received, SSLRECEIVEDSHUTDOWN will be set,
       for setting SSLSENTSHUTDOWN the application must however still call
       SSLshutdown(3) or SSLsetshutdown() itself.

RETURN VALUES
       SSLsetshutdown() does not return diagnostic information.

       SSLgetshutdown() returns the current setting.
