 typedef int new_func(void *parent, void *ptr, CRYPTO_EX_DATA *ad,
                int idx, long argl, void *argp);
 typedef void free_func(void *parent, void *ptr, CRYPTO_EX_DATA *ad,
                int idx, long argl, void *argp);

=head1 DESCRIPTION

Several OpenSSL structures can have application specific data attached to them.
These functions are used internally by OpenSSL to manipulate application
specific data attached to a specific structure.

SSL_SESSION_get_ex_new_index() is used to register a new index for application
specific data.

SSL_SESSION_set_ex_data() is used to store application data at B<arg> for B<idx>
into the B<session> object.

SSL_SESSION_get_ex_data() is used to retrieve the information for B<idx> from
B<session>.

A detailed description for the B<*_get_ex_new_index()> functionality
can be found in L<RSA_get_ex_new_index(3)|RSA_get_ex_new_index(3)>.
The B<*_get_ex_data()> and B<*_set_ex_data()> functionality is described in
L<CRYPTO_set_ex_data(3)|CRYPTO_set_ex_data(3)>.

=head1 WARNINGS

The application data is only maintained for sessions held in memory. The
application data is not included when dumping the session with
i2d_SSL_SESSION() (and all functions indirectly calling the dump functions
like PEM_write_SSL_SESSION() and PEM_write_bio_SSL_SESSION()) and can
therefore not be restored.
