SUMMARY
The Windows Sockets specification (Winsock) version 1.1 provides for an
application to set the SO_DEBUG option by calling the setsockopt() API.
Although a call to set this option succeeds (doesn't return SOCKET_ERROR),
the setting is ignored by all Microsoft Windows Sockets implementations.
This includes the Winsock implementations for:
- Windows for Workgroups 3.11 (MS TCP/IP-32)
- Windows NT 3.1, 3.5, 3.51
- Windows 95
- LAN Manager 2.2c
