div() & ldiv() behavior?

[Steve Emmerson]

Hi,

Would someone who knows please tell me the behavior of div() and ldiv()?

My POSIX book says nothing, and my K&R2 only states that they return
the quotient and remainder of the `numer' and `denom' arguments in the
`quot' and `rem' members of their associated structure types.

I know what this means when both arguments are positive, but I'm uncertain
what this means for the other three cases.  I you would tell me, I would
appreciate it.

Thanks in advance.
