HAL Exports Added For Version 5.1

This page lists the three exports that were added to the Windows HAL for version 5.1, i.e., for Windows XP. They are exported only from the x86 builds. All are still exported as of version 6.3, but starting with version 6.2 they are exported only as forwards to the kernel (which is where all versions of 64-bit Windows export them from).
