| /* 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 ppc. 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. |
