NAME
SSL_CTX_free —
free an allocated SSL_CTX
object
SYNOPSIS
#include
<openssl/ssl.h>
void
SSL_CTX_free(SSL_CTX
*ctx);
DESCRIPTION
SSL_CTX_free()
decrements the reference count of ctx, and removes the
SSL_CTX object pointed to by ctx
and frees up the allocated memory if the reference count has reached 0. If
ctx is a NULL pointer, no action
occurs.
It also calls the free(3)ing procedures for indirectly affected items, if applicable: the session cache, the list of ciphers, the list of Client CAs, the certificates and keys.
WARNINGS
If a session-remove callback is set
(SSL_CTX_sess_set_remove_cb(3)), this callback will be called
for each session being freed from 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(ctx,
NULL) prior to calling
SSL_CTX_free().
