| 30 /* minidump_format.h: A cross-platform reimplementation of minidump-related | |
| 31 * portions of DbgHelp.h from the Windows Platform SDK. | |
| 32 * | |
| 33 * (This is C99 source, please don't corrupt it with C++.) | |
| 34 * | |
| 35 * This file contains the necessary definitions to read minidump files | |
| 36 * produced on x86. These files may be read on any platform provided | |
| 37 * that the alignments of these structures on the processing system are | |
| 38 * identical to the alignments of these structures on the producing system. | |
| 39 * For this reason, precise-sized types are used. The structures defined | |
| 40 * by this file have been laid out to minimize alignment problems by ensuring | |
| 41 * ensuring that all members are aligned on their natural boundaries. In | |
| 42 * In some cases, tail-padding may be significant when different ABIs specify | |
| 43 * different tail-padding behaviors. To avoid problems when reading or | |
| 44 * writing affected structures, MD_*_SIZE macros are provided where needed, | |
| 45 * containing the useful size of the structures without padding. | |
| 46 * | |
| 47 * Structures that are defined by Microsoft to contain a zero-length array | |
| 48 * are instead defined here to contain an array with one element, as | |
| 49 * zero-length arrays are forbidden by standard C and C++. In these cases, | |
| 50 * *_minsize constants are provided to be used in place of sizeof. For a | |
| 51 * cleaner interface to these sizes when using C++, see minidump_size.h. | |
| 52 * | |
| 53 * These structures are also sufficient to populate minidump files. | |
| 54 * | |
| 55 * These definitions may be extended to support handling minidump files | |
| 56 * for other CPUs and other operating systems. | |
| 57 * | |
| 58 * Because precise data type sizes are crucial for this implementation to | |
| 59 * function properly and portably in terms of interoperability with minidumps | |
| 60 * produced by DbgHelp on Windows, a set of primitive types with known sizes | |
| 61 * are used as the basis of each structure defined by this file. DbgHelp | |
| 62 * on Windows is assumed to be the reference implementation; this file | |
| 63 * seeks to provide a cross-platform compatible implementation. To avoid | |
| 64 * collisions with the types and values defined and used by DbgHelp in the | |
| 65 * event that this implementation is used on Windows, each type and value | |
| 66 * defined here is given a new name, beginning with "MD". Names of the | |
| 67 * equivalent types and values in the Windows Platform SDK are given in | |
| 68 * comments. | |
