Fun with NULL pointers, part 2Fun with NULL pointers, part 2Posted Jul 22, 2009 3:53 UTC (Wed) by jreiser (subscriber, #11027)In reply to: Fun with NULL pointers, part 2 by bartoldeman Parent article: Fun with NULL pointers, part 2 The null page is only really *needed* for vm86()...That is just not true [except of course for arguments regarding universality, or emulating every access to page 0 via SIGSEGV, etc.] I have written programs where having page 0 is essential (for elegance, or ease of maintenance, or time performance, or space performance, etc.), and I object to those programs becoming non-functional.
