Module Name:
ptdbgext.h
*WAS* kdextlib.h
Abstract:
Kernel Debugger extensions to allow the quick creation of CDB/Windbg
debugger extensions. Used in conjunction with the following:
transdbg.h - Minimal debugging extension helper macros
ptdbgext.h - Auto dump of classes and structures
_dbgdump.h - Used to define struct/class descriptors in 1 pass

21-Aug-1995 Milans Copied for use in Mup Kernel Extensions

// The FIELD_DESCRIPTOR data structure is used to describe the field in a structure sufficiently
// for displaying information during debugging. The three pieces of information that are required
// are 1) the name of the field, 2) the offset in the corresponding structure and 3) a type descriptor.
// The type descriptor covers most primitive types.
//
// There are some types that can benefit from some auxillary information in the descriptors. A
// case in point is the "enum" defeinition. Merely printing out a numerical value for an enum
// type will invariably force the person using these extensions to refer to the corresponding
// include file. In order to avoid this we will accept an additional array for enum types that
// contains a textual description of the numerical value. A "bit mask" type falls in the same
// category. For the puposes of this extension lib, a "enum" and "bit mask" may be
// interchanged. The key difference is that an "enum" will tested for a single value, while
// a "bit mask" will be testes using a bitwise OR against all values. The ENUM_VALUE_DESCRIPTOR
// and BIT_MASK_DESCRIPTOR are interchangable.
//
// The macros to define the necessary structures can be found in _dbgdump.h.
