You can find source code of undocumented functions in ReactOS, which uses similar code as the NT Kernel :

Calling the next thread (API) to run on processor (documentation needed)

I was reading the book Windows Internals 6th Edition Part 1, Chapter 5, Thread Selection and it states the following "Whenever a logical processor needs to pick the next thread to run, it calls the **KiSelectNextThread scheduler function**. " I tried searching Google and Microsoft and could not find any help. Can someone tell me where I can find documentation on this API ? I would also like to find documentation on all available API that the kernel scheduler has to offer. Thanks in advance Victor

2021-02-20T16:34:10.507+00:00 I did have one further question to ask. If you take the following sentence "Whenever a logical processor needs to pick the next thread to run, it calls the KiSelectNextThread scheduler function. " literally its saying that the CPU calls this function but how does the CPU actually makes this call ?
