Hi Benny, Bug #1: PJ_SOL_TCP gives the wrong value in Windows. Or at least it does with my VC 2005 compiler. It seems that an "enum"ed symbol is not "#defined". Go figure. Bug #2: In Windows NT, pj_ioqueue_accept with a value of NULL for "local" will return an error if there is a connection immediately available instead of connecting to it. It looks like it's calling "getsockname" with a null address pointer. Request: It would be really cool if there was a PJ_TCP_NODELAY. Thanks, John Ridges
