=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);
|
|
|
|
int SSL_SESSION_set_ex_data(SSL_SESSION *s, int idx, void *arg);
|

|
|
void *SSL_SESSION_get_ex_data(const SSL_SESSION *s, int idx);

|
=head1 DESCRIPTION
|
|
|
|
SSL*_set_ex_data() functions can be used to store arbitrary user data into the
|
|
B<SSL_CTX>, B<SSL> or B<SSL_SESSION>. 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.
