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 arg for idx into the session object.
SSL_SESSION_get_ex_data() is used to retrieve the information
for idx from session.
A detailed description for the *_get_ex_new_index() functionality
can be found in RSA_get_ex_new_index(3). The *_get_ex_data() and
*_set_ex_data() functionality is described in CRYPTO_set_ex_data(3).
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.
