R-beta: question on dyn.loaded code

[Buyukisik, Osman (GEAE)]

Using R0.61.1 Alpha on hpux10.20 with patches I get :

> dyn.load("fn1.sl")
> dyn.load("fn2.sl")
> .C("negtwice",as.integer(2))
[[1]]
[1] -4

> .C("twice",as.integer(2))
[[1]]
[1] 4

I had to type the functions as "int" rather than void.
I will try the same at home on my redhat 4.2 linux box.

Cheers,
Osman
