/* 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.
