In gtkmm2 look at the documentation on the function Glib::SignalIO::connect() 
and the associated convenience funtion Glib::signal_io().connect(), which do 
what you want so far as signalling the presence of data to be read on a 
pipe/socket/filesystem with an open file descriptor.  To read the data you 
will need to use the standard Unix read() (if you are using a Unix-like OS), 
or some other library.
