Sadly, that doesn't mean what you think it means. You've declared a
function which takes a file_desciptor_source as a parameter. This is
known as "C++'s most vexing parse", after an article about it in the
book Effective C++. If you don't have that book, there's an article
about it here:

The errors that you're getting should have the type of 'in' as a
function, which is the clue. Also, if you use 'clang' it gives a
helpful warning.
