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.
The SSL_SESSION_get_ex_new_index() function is used to register a new
index for application specific data.
The SSL_SESSION_set_ex_data() function is used to store application
data at arg for idx into the session object.
The SSL_SESSION_get_ex_data() function is used to retrieve the informa‐
tion for idx from session.
A detailed description for the *_get_ex_new_index() functionality can
be found in RSA_get_ex_new_index(). The *_get_ex_data() and
*_set_ex_data() functionality is described in CRYPTO_set_ex_data().
RESTRICTIONS
The application data is only maintained for sessions held in memory.
The application data is not included when dumping the session with the
i2d_SSL_SESSION() function, as well as all functions indirectly calling
the dump functions, such as the PEM_write_SSL_SESSION() and
PEM_write_bio_SSL_SESSION()functions. It cannot be restored.
