Hi,

I am trying to work with the Toolbox in Think C and having trouble with 
polygons.  I am trying to load a number of polygons from a resource 
(actually, load the points and doing LineTo's to make polygons).  The problem 
is this:

In Quickdraw.h the pascal function OpenPoly is defined, but the rest of the 
polygon functions aren't.  I realize that openpoly is the only function that 
returns a value, but the other functions won't work.  If I use ClosePoly to 
end the polygon definition I get a compiler error: Invalid use of inline 
function.  What does that mean??

The code looks like:

void LoadLevel (level, theWell)
int level;
PolyHandle theWell[];
{
int notDone = 1;
Handle res;
res = GetResource ('LEVL', level);
if (!res) exit(1);
for (segments=0; notDone; segments++) {
 theWell[segments] = OpenPoly();
 MoveTo(*(*res+(8*segments)),*(*res+(8*segments+1)));
 LineTo(*(*res+(8*segments+2)),*(*res+(8*segments+3)));
 LineTo(*(*res+(8*segments+4)),*(*res+(8*segments+5)));
 LineTo(*(*res+(8*segments+6)),*(*res+(8*segments+7)));
 ClosePoly;
 if (*(*res+(8*segments+4)) == 0 && *(*res+(8*segments+5)) == 0) notDone=0;
 };
}

Anyone who cares to give me a hint is welcome (yes, I know the programming 
style is slightly crude, but it is a first shot at C).

thanks,

Matt Farmer
