[Live-devel] Reception Packet Information

[Dixon Siu]

Sorry to bother you again, Ross.

I wasn't clear on the doEventLoop issue. So in order to have my function
being executed by live.com's event loop every n microseconds, should I do
the following:
In main:
{
...
env->taskScheduler().scheduleDelayedTask(n,
getCurrentReceiverPacketInfo,data); // this will be executed once
env0>taskScheduler().doEventLoop(); // no return
}

The trick is that within getCurrentReceiverPacketInfo(), I should do this:
{
// perform information gathering
...
// at the end, schedule another task
env->taskScheduler().scheduleDelayedTask(n, getCurrentReceiverPacketInfo,
data); // this will be executed next
}

So it will be recursively executed by doEventLoop every n microseconds AND
does not affect the live.com's thread. The idea is kind of like
doGetNextFrame() in each source reading class, doGetNextFrame() perform the
reading, then at the very end, there is a scheduleDelayedTask() call to loop
back. Please correct me if I am wrong.

Regards,
Dixon
