How to detach socket from FILE?

Suppose I've got socket descriptor and have attached it to a FILE using
'fdopen()'. Now I want to 'fclose()' the FILE, but leave socket
open. According to FreeBSD manual pages, 'fclose()' will close the socket.

I think I can do something like this:

int s;
FILE* file;
s = dup(fileno(file));
... use s ...

But would 'dup' work as expected in RTEMS? Is there another/better way to
achieve the same goal?

Thanks in advance.
