KERNEL32 4.0 Named Exports

The table below lists all the functions that are first exported from KERNEL32 by name in version 4.0, i.e., for Windows 95 and Windows NT 4.0.

Version 4.0 is complicated by its use for two operating systems. The Windows that runs on DOS came first and is referred to below as Windows. The Windows that survives today began as Windows NT and is referred to below as NT even though it has long superseded the other Windows. Many KERNEL32 functions that were introduced for version 4.0 only ever appeared in the Windows stream. They are marked “Windows only”. Some were eventually picked up for the NT stream, even long after the Windows stream’s last version. Very many more Windows-only functions were only ever exported by ordinal, and are listed on the separate pages of Ordinal-Only Exports for versions 4.0, 4.10 and 4.90.

Since the ordering of build numbers means that both Windows 95 releases precede all Windows NT 4.0 releases, functions that do not appear as exports until the original Windows NT 4.0 might be described as beginning in Windows NT 4.0. For symmetry, they are instead marked as “NT-only in 4.0” if they are taken up for version 4.10, or as “NT only” if they are not exported from any later version in the Windows stream.

Most Windows-only functions seem never to have got documented, especially if their reason for existence was to support an exchange of functionality with the 16-bit KRNL386.DLL. These and other functions that appear to be completely undocumented are highlighted yellow.
