size_t CRYPTO_secure_used();
=head1 DESCRIPTION
pointer; implementations may allocate more space than initially
requested, in order to "round up" and reduce secure heap fragmentation.
+OPENSSL_secure_allocated() tells if a pointer is allocated in the secure heap.
+
CRYPTO_secure_used() returns the number of bytes allocated in the
secure heap.
