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(3) (and all functions indirectly calling the dump functions like PEM_write_SSL_SESSION(3) and PEM_write_bio_SSL_SESSION(3)) and can therefore not be restored.
