Module Name:
pebteb.w
Abstract:
Declarations of PEB and TEB, and some types contained in them.
Address the maintenance problem that resulted from PEB and TEB being
defined three times, once "native" in ntpsapi.w, and twice, 32bit and 64bit
in wow64t.w.
Author:
Jay Krell (JayKrell) April 2001

//
// This file is #included three times.
//
// 1) by ntpsapi.h, with no "unusual" macros defined, to declare
// PEB and TEB, and some types contained in them
// 2) by wow64t.h to declare PEB32 and TEB32, and some types contained in them
// 3) by wow64t.h to declare PEB64 and TEB64, and some types contained in them
//
// wow64t.h #defines the macro PEBTEB_BITS to guide the declarations.
//
#if defined(PEBTEB_BITS) /* This is defined by wow64t.h. */
/*
Any type that occurs in this header that changes size between 32bit and 64bit
platforms must have a #define here at the top and an #undef at the bottom.
Any type that is defined this header and changes size between 32bit and 64bit
platforms (structs with pointers), must have a #define and #undef for all
the "flavors" of name -- _FOO, FOO, PFOO, PCFOO, etc.
More "stable" types can be left manually defined three times in ntdef.w, wow64t.w, etc.
Less stable, maintenance problems, like PEB and TEB themselves, should be moved to this header.
Public types, as well, should remain in ntdef.w.
