Well the following appears to do what you want, if you are typing it at
a shell:

tail --follow --lines=+0  /path/to/file/your/watching

so you could always do the popen( cmd, "r" ) thing to leverage off
an existing solution. I just posted a code snipet on another thread,
i.e.

Re: OT: capturing stdout & stderr to a GtkText

to do exactly that. Be sure to read the restrictions though.
