In the description here, TYPE is used a placeholder for any of the OpenSSL datatypes listed in CRYPTO_get_ex_new_index(3).

These functions handle application-specific data for OpenSSL data structures.

() is a macro that calls CRYPTO_get_ex_new_index(3) with the correct index value.

() is a function that calls CRYPTO_set_ex_data(3) with an offset into the opaque exdata part of the TYPE object.
