When an R function is typed without (), the code that makes up the function will be returned

e.g. 

head
function (x, ...) 
UseMethod("head")
<bytecode: 0x0000022cd79ce9a8>
<environment: namespace:utils>

How can I do this for a function that is calling some C code?

Example

I am trying to see the (c) code that makes up the _pdftools_poppler_pdf_text function from pdftools package (which can be found by running pdftools:::poppler_pdf_text, which itself comes from the exported function pdf_text)

i.e.

pdftools:::poppler_pdf_text

Returns

function (x, opw, upw) 
{
    .Call("_pdftools_poppler_pdf_text", PACKAGE = "pdftools", 
        x, opw, upw)
}
<bytecode: 0x0000022ce8bff450>
<environment: namespace:pdftools>

How can I see the (c) code that makes up _pdftools_poppler_pdf_text ?
