Assuming I could buy it, does it cover toLua? I use that like, all the time. It's not in the ToC, but maybe it's hidden somewhere?

Will one of you peoples buy it for me? I'll send you the money (plus a little gratitude ;-) ) through PayPal. 

Nah, you won't do that. Is there any other place I can get it from?

Thanks!

I've been writing Lua and Lua from C code about everyday for a year
now and I still find PiL invaluable.  Just yesterday in fact I looked
up how to write an 'ipairs' like function from C using userdata (p.
261).  If you look the book up on amazon, you can see the table of
contents.  A good portion of the book is on the C stuff.

I've been reluctant to buy that because I thought it only covered the
basics of Lua coding, like, not the C API... But now that you say it
does, I have some questions:

1) What does it cover the most? I already know most of the "plain Lua"
part of it, I've made 2 games for the PSP Lua Player.
2) Is it the best book about it out there?

And back to the subject, it prints out just a number '1'... Looking at
the code, it seems it can either be a userdata or a table, so it's a
userdata... But what does the '1' mean?

Thanks for everything, Mr. Smith!

I would highly recommend picking up programming in Lua.  It has all
kind of stuff in there like this.  You will learn Lua much faster!
