1. you can do in with 'stat' and supplying a filename.

2. if the file is already open there's a better way:
     remember that any i/ofstream object has a pointer to
     a 'filebuf' object (the one that does the real job)
     you access this function with rdbuf().

     Example:
            ofstream   fout("file.ext");
             int  fd = fout.rdbuf()->fd();      // returns EOF if file
isn't open.

             // now you can use all the C functions that take file
descriptor.
             fstat(fd, .....);



Eyal.
