Hardly edifying :).
Much better would ve the explicit compare:
while((entry = getutxent()) != NULL)
But even that implies the programmer isn’t capable of differentiating = and ==.
My version of that is "while (0!=(entry=getutxevent()))".
(Of course, that assumes NULL is 0, but I don't think I've run into any
architecture so braindead as to not have NULL=0.)
