Fwd: HXThreadedSocket

Hi All,

Could someone please take a quick look at my question? This is quite
important. In relation to it, I would also like to know the difference
between IHXSocket and CHXSocket. Where is the function IHXSocket::ReadFrom
which is called in HXThreadedSocket::HandleRead( ) actually implemented?  I
really appreciate your help.

All the best,

Mahmoud

Dear All,

First of all I would like to thank you a lot (especially Jyotsana, Greg, and
Eric) for your constant support, this mailing list has been very helpful and
at the same time really informative.

I have a question regarding how packets make it through from the low-level
socket implementation in HXThreadedSocket, to the (RTP/UDP) transport layer
(with m_pOwner->ReadFromDone(...) in rtspclnt.cpp) and finally reach the
"application" layer. From what I know,  this is roughly what happens:

1) The UDP sockets are created with
RTSPClientProtocol::CreateUDPSockets(...), which is called in InitSockets(
).

2) In the net thread, the chain HXThreadedSocket::EventPending(...),
HandleRead( ), m_pSock->ReadFrom(...), m_inbound.AddTail(pBuf, pAddr) gets
executed (for read events).

HERE IS MY MISSING LINK, where does this m_inbound structure get read again
i.e. what happens between this point and m_pOwner->ReadFromDone(...) in
RTSPClientProtocol::UDPResponseHelper::EventPending(...)? Where do the
packets (pBuf) get dequeued from m_inbound and then reach this point to be
passed to the transport layer?

Thank you again,

Mahmoud Hammoud
