[R] Looking for .Call functions

In my ongoing quest to track down the source of an error (see message "[R] optim error in arima" above), I find in the cource code for arima0 the following:

     arma0f <- function(p) {
         par <- as.double(fixed)
         par[mask] <- p
         .Call("arma0fa", G, par, PACKAGE = "stats")

I would like to know what the function "arma0f" does.  Does the above mean that there is a function called "arma0fa" somewhere in R?  Where is it?  I couldn't find anything in Rinternals.h.
