HAL Version 5.1 Exports

This page lists the three exports that were added to the Windows HAL for version 5.1, i.e., for Windows XP. All are still exported as of version 6.1. None are exported from any x64 builds (but are instead exported from x64 builds of the kernel). One of the functions, highlighted yellow below, is undocumented.
