SSL_CTX_FREE(3)            Library Functions Manual            SSL_CTX_FREE(3)

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().

HISTORY
     SSL_CTX_free() first appeared in SSLeay 0.5.1 and has been available
     since OpenBSD 2.4.
