[PD-dev] [PD] libpd netreceive

[Peter Brinkmann]

Hi Thomas,
There's no mailing list for libpd, but there is a forum:
http://createdigitalnoise.com/categories/pd-everywhere In any case, this
does seem like a question for pd-dev, so we're in the right place :)

About sys_microsleep, there are two potential problems that I'm concerned
about about: The first is that it might block, but that doesn't seem to be
the case since it's being called in the audio callback. The second concern
is that I'm not sure how this low-level access to network sockets might
behave on Android (which requires special permissions for internet access).
I'm expecting that it'll be okay, but we need to make sure. Please let me
know how it goes!
Best,
     Peter
