R help - Sep 2003 - Parsing R matrix to C

I'm developing a C dll to use as a package in R. I need to parse a R Matrix
as
a parameter to a function in a dll. I?d like to know how can I use the Sexp 
type and how to handle this as a matrix in the C code.

Sorry for the bad english.

Thanks,

Daniel Ielpo

There are several examples in the R sources, just read the code and go on.
