Using @cfunction inside a function

General Usage
1

Hello,

I have a function like this:

function f(dim::Integer, pdf::Function)
  ......
  function pdf_j(xptr, distr)
    x = map(i -> unsafe_load(xptr, i), 1:dim)
    return pdf(x)::Cdouble
  end
  pdf_c = @cfunction(
    pdf_j, 
    Cdouble, 
    (Ptr{Cdouble}, Ptr{UNUR_DISTR})
  )
  ......
end

That does not work: pdf_j undefined, Julia says.

So I tried:

  pdf_c = @cfunction(
    (xptr, distr) -> pdf(map(i -> unsafe_load(xptr, i), 1:dim))::Cdouble, 
    Cdouble, 
    (Ptr{Cdouble}, Ptr{UNUR_DISTR})
  )

but this time Julia says dim undefined.

Could you help please?

Ok, I get it: $pdf_j.
