thread id and thread handle

NTDEV

Hi,
is there a way of retrieving thread id to thread handle (and vice versa) in
kernel or user mode ?

In user space OpenThread gives you a handle from an id, and GetThreadId does
the inverse. For the kernel the functions are undocumented.

ok this is outside this group topic but toolhelp32 library seems to do the
trick.
