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).
