- Demonstration of the Windows Sockets API
- SUMMARY
- =======
- The WSOCK sample demonstrates the basics of sockets programming,
- specifically for Windows Sockets. It demonstrates how to accept incoming
- connections (using the Windows Sockets Asynchronous Extension APIs, threads,
- and traditional BSD-style blocking calls) and how to connect to remote
- hosts. Once connected, you can send a text string to the remote host. WSOCK
- also allows the user to view information on a user-entered host name.
- WSOCK demonstrates how to use AcceptEx which is a Microsoft specific
- extension to Windows Sockets and which is only supported on Windows NT.
- MORE INFORMATION
- ================
- For the sample to operate correctly, the TCP/IP protocol must be properly
- installed. Also, if two machines are used over a network, both machines must
- have a HOSTS text file (for Windows NT machines, this file is located in
- %SYSTEMROOT%SYSTEM32DRIVERSETCHOSTS; for Windows for Workgroups
- machines, this file is located in C:/WINDOWS/HOSTS). Within each HOSTS file,
- both the remote and local addresses of both machines must be listed.
- WSOCK can run on a single machine (execute two copies of WSOCK) or over a
- network with two machines. The following example explains how two separate
- machines over a network would test WSOCK:
- 1. Machine "Bob" executes a copy of WSOCK.
- 2. Machine "Fred" executes a copy of WSOCK.
- 3. Machine "Bob" chooses one of the Listen menu options (under WinSock)
- [Listen (Blocking), Listen With Threads, or Async Listen].
- 4. Machine "Fred" selects the Connect menu option (under WinSock).
- 5. Machine "Bob" enters "12" as a TCP port number.
- 6. Machine "Bob" waits for a connection.
- 7. Machine "Fred" enters "Bob" as the host name to connect to.
- 8. Machine "Fred" enters "12" as a TCP port number.
- Both machines are now connected and can send strings back and forth by using
- the WinSock Send Message menu option.
- If Bob exits WSOCK while there is a connection, Fred receives a message box
- notification.
