[R] passing a matrix to C++ with .C()?

It seems that it is possible to pass a matrix to C++ by using .C()
The R part of the interface should be something like:
('C++function', matrix, numberRows, numberColumns )
The C++ part of the interface could be something like
void C++( double matrix, int numberRows, numberColumns )
but C++ requires to indicate the number of columns, that is, instead of
matrix, it should be double matrix[ numberColumns ]...
This does not look like the right thing to do though.
Can anyone help me with this?
