=head1 NAME

SSL_clear - reset SSL object to allow another connection

=head1 SYNOPSIS

 #include <openssl/ssl.h>

 int SSL_clear(SSL *ssl);

=head1 DESCRIPTION

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

=head1 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 B<open>, it is considered bad and will be removed
from the session cache, as required by RFC2246. A session is considered open,
if L<SSL_shutdown(3)|SSL_shutdown(3)> was not called for the connection
or at least L<SSL_set_shutdown(3)|SSL_set_shutdown(3)> was used to
set the SSL_SENT_SHUTDOWN state.
