For nroff, turn off justification. Always turn off hyphenation; it makesway too many mistakes in technical documents.
"NAME"
SSL_clear - reset SSL object to allow another connection
"SYNOPSIS"
Header "SYNOPSIS" .Vb 1
#include <openssl/ssl.h>
\&
int SSL_clear(SSL *ssl);
.Ve
"DESCRIPTION"
Header "DESCRIPTION" Reset ssl to allow another connection. All settings (method, ciphers,
BIOs) are kept.
"NOTES"
Header "NOTES" SSL_clear is used to prepare an \s-1SSL\s0 object for a new connection. While all
settings are kept, a side effect is the handling of the current \s-1SSL\s0 session.
If a session is still open, it is considered bad and will be removed
from the session cache, as required by \s-1RFC2246\s0. 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 \s-1SSL_SENT_SHUTDOWN\s0 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 \s-1SSL\s0 client object will use a TLSv1 client method for the next handshake and a \s-1SSL\s0 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"
Header "WARNINGS" \fISSL_clear() resets the \s-1SSL\s0 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 when opening a new session (or reusing
an old one) with the same peer that shares these settings.
\fISSL_clear() is not a short form for the sequence
\fISSL_free\|(3); SSL_new\|(3); .
"RETURN VALUES"
Header "RETURN VALUES" The following return values can occur:
"0" 4
The SSL_clear() operation could not be performed. Check the error stack to
find out the reason.
"1" 4
Item "1" The SSL_clear() operation was successful.
\fISSL_new\|(3), SSL_free\|(3), \fISSL_shutdown\|(3), SSL_set_shutdown\|(3), \fISSL_CTX_set_options\|(3), ssl\|(3), \fISSL_CTX_set_client_cert_cb\|(3)
