.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "SSL_CTX_FREE 3ossl"
SSL_CTX_FREE 3ossl "2023-09-19" "3.0.11" "OpenSSL"
For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
"NAME"
SSL_CTX_free - free an allocated SSL_CTX object
"SYNOPSIS"
Header "SYNOPSIS" .Vb 1 #include <openssl/ssl.h> \& void SSL_CTX_free(SSL_CTX *ctx); .Ve
"DESCRIPTION"
Header "DESCRIPTION" \fBSSL_CTX_free() decrements the reference count of ctx, and removes the \s-1SSL_CTX\s0 object pointed to by 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 ctx is \s-1NULL\s0 nothing is done.

"WARNINGS"
Header "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 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, \s-1NULL\s0) prior to calling SSL_CTX_free().
"RETURN VALUES"
Header "RETURN VALUES" \fBSSL_CTX_free() does not provide diagnostic information.
"SEE ALSO"
Header "SEE ALSO" \fBSSL_CTX_new\|(3), ssl\|(7), \fBSSL_CTX_sess_set_get_cb\|(3)
