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_get_ex_new_index() is used to register a new index for
application specific data.
SSL_set_ex_data() is used to store application data at arg
for idx into the ssl object.
SSL_get_ex_data() is used to retrieve the information for
idx from ssl.
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).
EXAMPLES
An example on how to use the functionality is included in
the example verify_callback() in SSL_CTX_set_verify(3).
