1=pod 2 3=head1 NAME 4 5SSL_CTX_free - free an allocated SSL_CTX object 6 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 reference count has reached 0. 17 18It also calls the free()ing procedures for indirectly affected items, if 19applicable: the session cache, the list of ciphers, the list of Client CAs, 20the certificates and keys. 21 22If B<ctx> is NULL nothing is done. 23 24=head1 WARNINGS 25 26If a session-remove callback is set (SSL_CTX_sess_set_remove_cb()), this 27callback will be called for each session being freed from B<ctx>'s 28session cache. This implies, that all corresponding sessions from an 29external session cache are removed as well. If this is not desired, the user 30should explicitly unset the callback by calling 31SSL_CTX_sess_set_remove_cb(B<ctx>, NULL) prior to calling SSL_CTX_free(). 32 33=head1 RETURN VALUES 34 35SSL_CTX_free() does not provide diagnostic information. 36 37=head1 SEE ALSO 38 39L<SSL_CTX_new(3)>, L<ssl(7)>, 40L<SSL_CTX_sess_set_get_cb(3)> 41 42=head1 COPYRIGHT 43 44Copyright 2000-2016 The OpenSSL Project Authors.
