The write symbol in the example program is an object of the type 
fem::common_writer (you can see the declaration on line 70). Obviously, 
you will have to name the type explicitly, provide a using declaration, 
or rely on type inference when you declare a value of that type. write 
is just the name of the object though so you could call it anything you 
like. Perhaps:

fem::common_writer gregory(cmn);

or

fem::common_writer louise(cmn);

If you want to be able to use the POSIX write function in the same 
program you could get it with ::write rather than just write.
