Dereferencing NULL

[Root Boy Jim]

	Sometimes I think that every C language course should include a section 
	on "The Use and Abuse of Null Pointers"... unfortunately, I have yet to
	see this mentioned in any such course's syllabus.
	
Hey, even *I* don't dereference NULL pointers! However I do think that
software should be tolerant when passed such items. I seem to remember
that `printf' would say `<null>' or something to that effect when invoked
as `printf("%s",0)' (Guy would say `printf("%s",(char *) 0)').

	Given the quality of too many C programs (and programmers), that title
	sounds like a thankless task at best....

Perhaps we should call you `The Talking Lint' :-)
