As far as I can tell, the C code contains the declaration "Signed
h_tid;".  So I would guess that hdr['h_tid'] returns a signed integer.
The next line masks it to a number between 0 and 2**32-1, so then -42
would become 0xffffffd5.  But I didn't actually check; please fix if
I'm wrong.


A bientôt,

Armin.
