I've just started using MacProtos.h, a copy of which I got from the info-mac
archives at sumex. (Or maybe UT rice, not certain.) I like it a lot, since I'm
compulsive about using what little typing C allows. (Yeah, I know, "Strong
typing is for people with weak memories." I used to quote that a lot before
ANSI C, but now that I can have type checking on parameters if I want it, well
isn't weak memories why we don't all program in binary right down on the bare
silicon? But I digress.) I've just encountered a problem.  

In trying to call FillRect(), I passed it the global "white" and it complained.
I looked everything up, and found that IM (I have the promo edition, the old
"phone book" I-III) gives the following declarations:

	TYPE  Pattern = PACKED ARRAY [0..7] OF 0..255;
	VAR white: Pattern;
	FillRect (r: Rect; pat: Pattern);

Think C 4's <Quickdraw.h> gives:

	typedef unsigned char Pattern[8];
	extern Pattern	white;

which makes "white" a "char *". MacProtos.h gives:

	pascal void FillRect(Rect *r, Pattern *pat);

which makes pat a "char * *" or "char * []". I believe that second parameter
should be "Pattern pat", not "*pat". I also found the same thing everywhere
that "Pattern" occurs in MacProtos.h. Am I missing something, like is Pattern a
struct in MPW C or older Think (LightSpeed) Cs, or has no-one used FillRect()
and MacProtos.h both in the same program?

Out of curiousity, how widely _is_ MacProtos.h used? As I said, I personally
love it, since it gives me a little more type checking that Think C has built
in for Mac traps.
