Not exactly no, but the code for __get_ro_socket is:

return (int)getfd (sockfd)->devicehandle->handle;

It doesn't check that it actually has a socket fd, so it seems likely
that if you gave it a file fd you would get the RISC OS file handle
back. If we were to implement a __get_ro_file, I suspect it would
probably be the exact same code. If it does work, then perhaps

#define __get_ro_file __get_ro_socket

would be useful in your code to indicate that you're expecting a file
and not a socket.
