7=head1 SYNOPSIS
8
9 #include <openssl/ssl.h>
10
11 void SSL_CTX_free(SSL_CTX *ctx);
12
13=head1 DESCRIPTION
14
15SSL_CTX_free() decrements the reference count of B<ctx>, and removes the
16SSL_CTX object pointed to by B<ctx> and frees up the allocated memory if the
17the reference count has reached 0.
18
19It also calls the free()ing procedures for indirectly affected items, if
20applicable: the session cache, the list of ciphers, the list of Client CAs,
21the certificates and keys.
22
23=head1 WARNINGS
24
25If a session-remove callback is set (SSL_CTX_sess_set_remove_cb()), this
26callback will be called for each session being freed from B<ctx>'s
27session cache. This implies, that all corresponding sessions from an
28external session cache are removed as well. If this is not desired, the user
29should explicitly unset the callback by calling
30SSL_CTX_sess_set_remove_cb(B<ctx>, NULL) prior to calling SSL_CTX_free().
