foldl(Fun, Acc0, Cache) -> Acc

Types

init(Args) -> opaque()

Types

Includes property {role, client | server}. Currently this is the only predefined property, there can also be user-defined properties. See also application environment variable session_cb_init_args.

Performs possible initializations of the cache and returns a reference to it that is used as parameter to the other API functions. Is called by the cache handling processes init function, hence putting the same requirements on it as a normal process init function. This function is called twice when starting the SSL application, once with the role client and once with the role server, as the SSL application must be prepared to take on both roles.
