More info about giochannel & spawning processes

[Vladimir Djokic <vladeck sezampro yu>]

   Good day,
   Developers. I want to make gtk2 frontend for wvdial, but I need more 
info about using giochannels and spawning processes (fork()/exec()). 
This is all new to me, so docs are not enough. :( If someone can give me 
links to examples/tutorials, or even source (that I can understand) of 
some app that uses these?

   Thank you for this off-topic help,
   Vladimir.
