Yes, that would appear to be correct.
There is an *FLTK1* example of using add_fd() here:
http://www.seriss.com/people/erco/fltk/#add_fd
Although FLTK2 has slightly different syntax, the use of add_fd
should be the same.
Note that this is a very unix specific technique that likely
won't work at all under Windows.
To support both platforms well, you probably want to use
a child thread that monitors the input stream, and passes data
through a common buffer to the parent (fltk) thread which would
use an FLTK timer to poll the buffer to read it, the two threads
agreeing on when to access the buffer using simple locking.
