[pulseaudio-discuss] [PATCH] Add support of callbacks for operation cancelation

[Favonia]

Dear all,

Here is a patch that should provide the functionality we want
(mentioned in http://lists.freedesktop.org/archives/pulseaudio-discuss/2012-May/013544.html)
without changing the current API too much. I am a beginner in
PulseAudio so it is likely that I made some terrible mistakes. Ideally
every async API call should take one extra callback for cancelation,
instead of setting up the callback after the API call; however this
will lead to a major API change.

Regards,
Favonia
