please review: simple winsock example for sending data over a nonblocking
socket

I put together a simple winsock example for sending data over a nonblocking
socket because i could not find such a simple example on the internet.
please tell me if you see any MEMORY LEAKS, RESOURSE MISUSE, or other
critical issues with this code: http://rafb.net/paste/results/mZAzaI55.html
I would like this to be perfect as i will use it over and over. Any
meaningfull and focused suggestions appreciated. In no case should this code
hang because of any kind of network or remote server issue. And in no case
should it leak memory or resources:
