[linux-audio-dev] [ot] How do GUI-libs notify the program of changes?

[Julien Claassen]

Hi all!
  I know it's completely OT, but I think there maybe people here, who could
help me.
  Problem is: I'm still on my libcui (character user interface) project and I
wonder:
  I push a button, slide a slider... How does the UI notify the program of
this change? How do Engine and UI communicate?
  Please anyone: HELP ME!
  Kindest regards
       Julien
