This sample illustrates the use of SOCK_RAW in Winsock 2.0 on Windows NT in
order to write an ICMP_ECHO utility (commonly seen in the 'ping' program on
various systems).
Usage:
ping <hostname/IP address> <packet size>
Sends ICMP echo requests to host specified by the first argument. If a
packet size is specified, a buffer of that size is sent. The default size
is 32 bytes.
