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.

() is used to register a new index for application specific data.

() is used to store application data at arg for idx into the ctx object.

() is used to retrieve the information for idx from ctx.

A detailed description for the () functionality can be found in RSA_get_ex_new_index(3). The () and () functionality is described in CRYPTO_set_ex_data(3).

SSL_CTX_get_ex_new_index(), SSL_CTX_set_ex_data(), and SSL_CTX_get_ex_data() first appeared in SSLeay 0.9.0 and have been available since OpenBSD 2.4.
