First, you don't need to 'create lang' for C. It is predefined language,
you can just use it.
Second, you need to download postgres source (or get it from CVS) to
write postgres functions in C.
You can get it from here for example;
ftp://ftp.postgresql.org/pub/source/v7.3.3
or look at postgresql.org for instructions on getting the source from CVS:
http://www.postgresql.org/docs/7.3/static/cvs.html
When you get the source code, look into the contrib directory - there is
a whole lot of code there that you can use as examples of creating
postgres functions in C
I hope, it helps...
