If bsearch is called with $nmemb == 0$, is $base$ required to point to a
legitimate array, or can it be $NULL$ ?

[A library I know of hangs in this case; I'd like to know if my code is broken,
or if the library is.]

A similar question arises for $qsort$; if one $qsort$'s 0 elements, is the
value of the array pointer required to point to a proper array, or is it
allowed to be $NULL$?
