=head1 NAME

SSL_CTX_get_ex_data, SSL_CTX_set_ex_data,
SSL_get_ex_data, SSL_set_ex_data
- Store and retrieve extra data from the SSL_CTX, SSL or SSL_SESSION

=head1 SYNOPSIS

#include <openssl/ssl.h>

void *SSL_CTX_get_ex_data(const SSL_CTX *s, int idx);

int SSL_CTX_set_ex_data(SSL_CTX *s, int idx, void *arg);

void *SSL_get_ex_data(const SSL *s, int idx);

int SSL_set_ex_data(SSL *s, int idx, void *arg);

=head1 DESCRIPTION

SSL*_set_ex_data() functions can be used to store arbitrary user data into the
B<SSL_CTX>, or B<SSL> object. The user must supply a unique index
which they can subsequently use to retrieve the data using SSL*_get_ex_data().

For more detailed information see L<CRYPTO_get_ex_data(3)> and
L<CRYPTO_set_ex_data(3)> which implement these functions and
L<CRYPTO_get_ex_new_index(3)> for generating a unique index.

=head1 RETURN VALUES

The SSL*_set_ex_data() functions return 1 if the item is successfully stored
and 0 if it is not.
The SSL*_get_ex_data() functions return the ex_data pointer if successful,
otherwise NULL.
