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  * Structures that are defined by Microsoft to contain a zero-length array
36  * are instead defined here to contain an array with one element, as
37  * zero-length arrays are forbidden by standard C and C++.  In these cases,
38  * *_minsize constants are provided to be used in place of sizeof.  For a
39  * cleaner interface to these sizes when using C++, see minidump_size.h.
40  *
41  * These structures are also sufficient to populate minidump files.
42  *
43  * These definitions may be extended to support handling minidump files
44  * for other CPUs and other operating systems.
45  *
46  * Because precise data type sizes are crucial for this implementation to
47  * function properly and portably in terms of interoperability with minidumps
48  * produced by DbgHelp on Windows, a set of primitive types with known sizes
49  * are used as the basis of each structure defined by this file.  DbgHelp
50  * on Windows is assumed to be the reference implementation; this file
51  * seeks to provide a cross-platform compatible implementation.  To avoid
52  * collisions with the types and values defined and used by DbgHelp in the
53  * event that this implementation is used on Windows, each type and value
54  * defined here is given a new name, beginning with "MD".  Names of the
55  * equivalent types and values in the Windows Platform SDK are given in
56  * comments.
