OBJ_cleanup() cleans up OpenSSLs internal object table: this should
be called before an application exits if any new objects were added
using OBJ_create().
OBJ_length() returns the size of the content octets of B<obj>.
OBJ_get0_data() returns a pointer to the content octets of B<obj>.
The returned pointer is an internal pointer which B<must not> be freed.
In OpenSSL versions prior to 1.1.0 OBJ_cleanup() cleaned up OpenSSLs internal
object table and was called before an application exits if any new objects were
added using OBJ_create(). This function is deprecated in version 1.1.0 and now
does nothing if called. No explicit de-initialisation is now required. See
L<OPENSSL_init_crypto(3)> for further information.
