The Windows for Workgroups (WFW) SDK contains additional files that can be used with the Windows version 3.1 SDK for WFW development. The WFW SDK includes the following components:

  • WFW SDK API Help file
  • Header (.H) files
  • Library (.LIB) files
  • Sample code
  • WFW debug binaries
  • WFW WDEB386.EXE files (WFW kernel mode debugger)
The WFW SDK is available on the Microsoft Developer's Network (MSDN) Level 2 CD set, beginning with the April 1994 edition.


The WFW SDK provides headers, libraries, and help for APIs in the following areas (which are new with WFW):

  • Networking:

    • WNet (connecting, browsing, sharing)
    • MNet (multiple-network driver interface)
    • Mailslots
    • Named pipes (asynchronous reads and writes)
  • NetDDE (networked DDE)
  • File Manager extensions
  • Common controls
The following are the WFW SDK samples and what they do:

  • MSLOT demonstrates the Mailslot APIs.
  • NPCLNT16 demonstrates the asynchronous named pipe APIs.
  • WFWAPI (in the NETAPI directory) demonstrates various WNet and MNet APIs.
  • DDESHARE (in the NETDDE directory) demonstrates the NDde APIs. This is the source code to the DDESHARE utility included with the WFW Resource Kit.

  • Microsoft Windows Software Development Kit 3.1
  • Microsoft Windows Software Development Kit 3.11
