=head1 NAME
SSL_free - free an allocated SSL structure
=head1 SYNOPSIS
#include <openssl/ssl.h>
void SSL_free(SSL *ssl);
=head1 DESCRIPTION
SSL_free() decrements the reference count of B<ssl>, and removes the SSL
structure pointed to by B<ssl> and frees up the allocated memory if the
reference count has reached 0.
If B<ssl> is NULL nothing is done.
=head1 NOTES
SSL_free() also calls the free()ing procedures for indirectly affected items, if
applicable: the buffering BIO, the read and write BIOs,
cipher lists specially created for this B<ssl>, the B<SSL_SESSION>.
Do not explicitly free these indirectly freed up items before or after
calling SSL_free(), as trying to free things twice may lead to program
failure.
The ssl session has reference counts from two users: the SSL object, for
which the reference count is removed by SSL_free() and the internal
session cache. If the session is considered bad, because
L<SSL_shutdown(3)|SSL_shutdown(3)> was not called for the connection
and L<SSL_set_shutdown(3)|SSL_set_shutdown(3)> was not used to set the
SSL_SENT_SHUTDOWN state, the session will also be removed
from the session cache as required by RFC2246.
=head1 RETURN VALUES
SSL_free() does not provide diagnostic information.
L<SSL_new(3)|SSL_new(3)>, L<SSL_clear(3)|SSL_clear(3)>,
L<SSL_shutdown(3)|SSL_shutdown(3)>, L<SSL_set_shutdown(3)|SSL_set_shutdown(3)>,
L<ssl(3)|ssl(3)>
