=head1 NAME
|
|
|
|
SSL_CTX_free - free an allocated SSL_CTX object
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/ssl.h>
|
|
|
|
void SSL_CTX_free(SSL_CTX *ctx);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
SSL_CTX_free() decrements the reference count of B<ctx>, and removes the
|
|
SSL_CTX object pointed to by B<ctx> and frees up the allocated memory if the reference count has reached 0.
|
|
|
|
It also calls the free()ing procedures for indirectly affected items, if
|
|
applicable: the session cache, the list of ciphers, the list of Client CAs,
|
|
the certificates and keys.
|
|
|
|
If B<ctx> is NULL nothing is done.
|
|
|
|
=head1 WARNINGS
|
|
|
|
If a session-remove callback is set (SSL_CTX_sess_set_remove_cb()), this
|
|
callback will be called for each session being freed from B<ctx>'s
|
|
session cache. This implies, that all corresponding sessions from an
|
|
external session cache are removed as well. If this is not desired, the user
|
|
should explicitly unset the callback by calling
|
|
SSL_CTX_sess_set_remove_cb(B<ctx>, NULL) prior to calling SSL_CTX_free().
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
SSL_CTX_free() does not provide diagnostic information.
