/* minidump_format.h: A cross-platform reimplementation of minidump-related
* portions of DbgHelp.h from the Windows Platform SDK.
*
* (This is C99 source, please don't corrupt it with C++.)
*
* This file contains the necessary definitions to read minidump files
* produced on amd64. These files may be read on any platform provided
* that the alignments of these structures on the processing system are
* identical to the alignments of these structures on the producing system.
* For this reason, precise-sized types are used. The structures defined
* by this file have been laid out to minimize alignment problems by ensuring
* ensuring that all members are aligned on their natural boundaries. In
* In some cases, tail-padding may be significant when different ABIs specify
* different tail-padding behaviors. To avoid problems when reading or
* writing affected structures, MD_*_SIZE macros are provided where needed,
* containing the useful size of the structures without padding.
*
* Structures that are defined by Microsoft to contain a zero-length array
* are instead defined here to contain an array with one element, as
* zero-length arrays are forbidden by standard C and C++. In these cases,
* *_minsize constants are provided to be used in place of sizeof. For a
* cleaner interface to these sizes when using C++, see minidump_size.h.
*
* These structures are also sufficient to populate minidump files.
*
* These definitions may be extended to support handling minidump files
* for other CPUs and other operating systems.
*
* Because precise data type sizes are crucial for this implementation to
* function properly and portably in terms of interoperability with minidumps
* produced by DbgHelp on Windows, a set of primitive types with known sizes
* are used as the basis of each structure defined by this file. DbgHelp
* on Windows is assumed to be the reference implementation; this file
* seeks to provide a cross-platform compatible implementation. To avoid
* collisions with the types and values defined and used by DbgHelp in the
* event that this implementation is used on Windows, each type and value
* defined here is given a new name, beginning with "MD". Names of the
* equivalent types and values in the Windows Platform SDK are given in
* comments.
