DOCERR: Setting of SO_DEBUG Option Is Ignored by Winsock Apps

ID: Q138965

The information in this article applies to:

Microsoft Windows Software Development Kit (SDK) versions 3.1, 3.11
Microsoft Win32 Software Development Kit (SDK), versions 3.1, 3.5, 3.51, 4.0

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
