Vincent thanks for the link, I was aware of the win32 port of pthreads however
since I've never looked deeply into it I put a question mark to it :)

Ian - since windows itself doen't have the UNIX style sockets mechanism, I was
thinking of implementing functionality using only the WSA API to provide
TCP/IP communication to a server (local or remote).
If my understanding is correct than trying to rewrite my own implementation of
writev() with multiple write() functions would be inefficient and I wouldn't
garner the true benefits of Scatter/Gather. I was looking into implementing
this using either the ReadFileScatter WriteFileGather functions - which
require page alignment for the buffers....or I've been leaning towards using
WSASend and WSARecv which as similar to the writev/readv mechanism on POSIX.
Please correct me on any of the above.....enlighten me....and give me nirvana
haha :)
Bye for now
