Re: [Beepcore-c-users] Mysterious socket error

[Lei Z. <lz...@ju...>]

Looks like your TCP connection is broken.  revents=0x19/0x19 means 
POLLIN | POLLERR | POLLHUP.

I've been fiddling with beepcore-c for a few months, haven't noticed 
frames getting lost - can you tell how to trigger that kind of error?

Thanks,
Lei
