/* 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++.)
 *
 * 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.
