Wireshark · Ethereal-dev: Re: [Ethereal-dev] what does sync_mode mean??

["Guy Harris" <gharris@xxxxxxxxx>]

It means the mode used for "Update list of packets in real time" captures,
in which there are two processes - one that captures the packets, writes
them to a file, and sends to the other process over a pipe messages saying
that a certain number of packets have been added to a file, and one that
receives those messages, reads packets from the file, and updates the
display.
