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_CTX_get_ex_new_index() is used to register a new index for application specific data.
SSL_CTX_set_ex_data() is used to store application data at arg for idx into the ctx object.
SSL_CTX_get_ex_data() is used to retrieve the information for idx from ctx.
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).
