SUMMARY
=======
The MCASTIP samples demonstrate the basic multicast sequence of operations
in WinSock 1 (setsocketopt) and WinSock 2 (WSAJoinLeaf). The sample also
illustrates IPv4 and IPv6 multicasting.

PLATFORM SUPPORTED
=================
Windows NT 4, Windows 2000, and Windows 95/98. Note that for Windows 95,
"Winsock 2 Update for WinSock 2" is required in order to run MCASTWS2
(please see http://support.microsoft.com/support/platformsdk/networking/Downloads.asp).
RUNNING THE SERVER AND CLIENT APPLICATIONS
==========================================
To build, type "nmake" at the command line.
To run the samples, please follow the usage specified below
mcastws1.exe [options]
Options:
-b str String address to bind to
-c Connect before sending?
-i str Local interface to join groups
-j Don't join the multicast group
-l 0/1 Turn on/off loopback
-m str Multicast address to join
-n int Number of messages to send/receive
-p int Port number to use
The default port is: 25000
-r Use raw sockets
-s Act as server (send data); otherwise
receive data.
-t int Set multicast TTL
-u Set SO_REUSEADDR
-z int Size of the send/recv buffer
mcastws2.exe [options]
Options:
-i addr Local address to bind to
-l 0/1 Disable/enable loopback
-m addr Multicast address to join
-n int Send/recv count
-p int Port number
-s Act as sender; default is receiver
-t int Set multicast TTL
-z int Buffer size (in bytes)
