NetBSD 6.1.5 - man page for ssl_clear (netbsd section 3)

SSL_clear(3)				     OpenSSL				     SSL_clear(3)

NAME
       SSL_clear - reset SSL object to allow another connection

LIBRARY
       libcrypto, -lcrypto

SYNOPSIS
	#include <openssl/ssl.h>

	int SSL_clear(SSL *ssl);

DESCRIPTION
       Reset ssl to allow another connection. All settings (method, ciphers, BIOs) are kept.

NOTES
       SSL_clear is used to prepare an SSL object for a new connection. While all settings are
       kept, a side effect is the handling of the current SSL session.	If a session is still
       open, it is considered bad and will be removed from the session cache, as required by
       RFC2246. A session is considered open, if SSL_shutdown(3) was not called for the
       connection or at least SSL_set_shutdown(3) was used to set the SSL_SENT_SHUTDOWN state.

       If a session was closed cleanly, the session object will be kept and all settings
       corresponding. This explicitly means, that e.g. the special method used during the session
       will be kept for the next handshake. So if the session was a TLSv1 session, a SSL client
       object will use a TLSv1 client method for the next handshake and a SSL server object will
       use a TLSv1 server method, even if SSLv23_*_methods were chosen on startup. This will
       might lead to connection failures (see SSL_new(3)) for a description of the method's
       properties.

WARNINGS
       SSL_clear() resets the SSL object to allow for another connection. The reset operation
       however keeps several settings of the last sessions (some of these settings were made
       automatically during the last handshake). It only makes sense for a new connection with
       the exact same peer that shares these settings, and may fail if that peer changes its
       settings between connections. Use the sequence SSL_get_session(3); SSL_new(3);
       SSL_set_session(3); SSL_free(3) instead to avoid such failures (or simply SSL_free(3);
       SSL_new(3) if session reuse is not desired).

RETURN VALUES
       The following return values can occur:

       0   The SSL_clear() operation could not be performed. Check the error stack to find out
	   the reason.

       1   The SSL_clear() operation was successful.

       SSL_new(3), SSL_free(3), SSL_shutdown(3), SSL_set_shutdown(3), SSL_CTX_set_options(3),
       ssl(3), SSL_CTX_set_client_cert_cb(3)
