csocket - connect() needs to have a timeout mechanism (for TCP-connection drop)

[uhurden]

Hi cybergarage,

I have been using cyberlink in iOS project for a while, and I noticed in some networks I have issue with device discovery.
I narrowed down an issues and found that after parsing SSD-header, when ssdp listener thread is trying to retrieve a device description it just blocks on connect, in the case when TCP-connection gets dropped on RST.
So I think you should also has a timeout mechanism on connect().

(I resolved it by setting a socket to non-blocking mode, then using select() with timeout, and after select returns, setting the socket back to blocking mode)
