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.
