Based on the docs kernel mode drivers would call KeWaitForMultipleObjects instead it appears. User space should just call WaitForMultipleObjects. While NtWaitForMultipleObjects and ZwWaitForMultipleObjects exist they seem to be undocumented which means they probably have funky behavior. Anything in KernelBase.dll is a pretty thin wrapper that I'd be hesitant to call Win32 so much as "really thin syscall wrapper"
