SSL_CTX_sessions() returns a pointer to the lhash databases containing the internal session cache for

       SSL_CTX_sessions - access internal session cache

       The sessions in the internal session cache are kept in an LHASH(3) type database. It is possible to
       directly access this database e.g. for searching. In parallel, the sessions form a linked list which is
       maintained separately from the LHASH(3) operations, so that the database must not be modified directly
       but by using the SSL_CTX_add_session(3) family of functions.

SSL_CTX_sessions() returns a pointer to the lhash of SSL_SESSION.
