Finding NULL byte in a long

[Doug]

I know this has been on the net before, since I thought I saved it,
but can't find it now.  Anyway, could someone tell me what the
C expression is that tells you if a long has a NULL byte in it.
This is without masking each byte and testing it for 0.  It is very
clever and non-obvious.  Thanks.
