I suppose it depends on just what you mean by "in general".

A conforming implementation *could* always print the mathematically
correct value of a 64-bit unsigned long argument when printf is
called with a 32-bit "%u" format.  I could speculate about how
this might work, but it doesn't really matter.  Probably few if
any implementations behave this way, but the nature of undefined
behavior is that there is no behavior that violates the C standard.

And of course the best advice is "don't do that".
