Module Name:
ntrtlp.h
Abstract:
Include file for NT runtime routines that are callable by both
kernel mode code in the executive and user mode code in various
NT subsystems, but which are private interfaces.
Author:
David N. Cutler (davec) 15-Aug-1989
Environment:
These routines are statically linked in the caller's executable and
are callable in either kernel mode or user mode.
