What kind of julia object translates to C's FILE*

What kind of a Julia object should I pass in as FILE *stream ? Ideally I’d be able to use either a file or an in-memory IOStream .

A Libc.FILE object, which you can create from an io::IO object (such as a file or a pipe) by f = Libc.FILE(io). (I think you have to manually call close(f) when you are done with it, because the constructor duplicates the file descriptor (julia#10535)?)
