and what about truecrypt volume? The point is that when the

No, crypt_get_type() should return NULL in this case ("unknown").
This is documented value.

There is another API i do not remember at the moment than return
undocumented NULL in this situation.
For unknown type the query operations are not defined (resp. you get NULL)
because itnerenaly it is is nor (yet) recognised.
But yes, it should be probably unified and documented better (NULL
seems to missing in doc in some query commands).
(In fact, underlying device cannot disapper if in use - there is still
(in kernel) some reference used in maping table but userspace behaves
diferently seems.)
