As far as I can tell it does not actually. This is a compatibility
function for od unixes and the name is literrally 'get descriptor table
size' so I suppose that it once returned the size of the array allocated
for the process to store file descritptors into.

So I supose that the only sensible approach is to call the function and
check that it returns a sane value.
