NAME
SSL_free —
free an allocated SSL
structure
SYNOPSIS
#include
<openssl/ssl.h>
void
SSL_free(SSL
*ssl);
DESCRIPTION
SSL_free()
decrements the reference count of ssl, and removes the
SSL structure pointed to by ssl
and frees up the allocated memory if the reference count has reached 0.
NOTES
SSL_free() also calls the
free(3)ing procedures for indirectly affected items, if applicable:
the buffering BIO, the read and write
BIOs, cipher lists specially created for this
ssl, the
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
SSL_shutdown(3) was not called for the connection and
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.
RETURN VALUES
SSL_free() does not provide diagnostic
information.
