Re: [Vala] C Integration, it's cool

Thanks Rodrigo for posting!!!

I tried your technique and i can pass at least integers and
strings (as const char*) to software written in c.  (I have
not tried sending across large amounts of data in arrays,
or anything like that.)

Is this written up on http://valadoc.org anywhere?

(I tried a very naive search on "extern" but only got External.....)
(And i guess i should point out that your decl below no
doubt was extern but dropped a character in copying.)

Anyhow, thanks again, this is a very big help to me because
the body of c code is very very large, and it is so useful
to be able to tap into it.

(PS: in case it makes any difference, i'm using vala 0.14 in ubuntu 11.10.)
