You can use winsock functions in the normal (socket) way to write
icmp packets out.  Unfortunately the winsock functions are
somewhat of a hack for reading back packets.  It appears that
you only get packets back in a recv that are a response to
a ping icmp packet you sent out.  In other words, it's almost
completely unusable for reading icmps.

Winsock is incapable of reading arbitrary icmps so you would
need some other way to read icmps to make an icmp logger.
