-// minidump.h: A minidump reader.
-//
-// The basic structure of this module tracks the structure of the minidump
-// file itself. At the top level, a minidump file is represented by a
-// Minidump object. Like most other classes in this module, Minidump
-// provides a Read method that initializes the object with information from
-// the file. Most of the classes in this file are wrappers around the
-// "raw" structures found in the minidump file itself, and defined in
-// minidump_format.h. For example, each thread is represented by a
-// MinidumpThread object, whose parameters are specified in an MDRawThread
-// structure. A properly byte-swapped MDRawThread can be obtained from a
-// MinidumpThread easily by calling its thread() method.
-//
-// Most of the module lazily reads only the portion of the minidump file
-// necessary to fulfill the user's request. Calling Minidump::Read
-// only reads the minidump's directory. The thread list is not read until
-// it is needed, and even once it's read, the memory regions for each
-// thread's stack aren't read until they're needed. This strategy avoids
-// unnecessary file input, and allocating memory for data in which the user
-// has no interest. Note that although memory allocations for a typical
-// minidump file are not particularly large, it is possible for legitimate
-// minidumps to be sizable. A full-memory minidump, for example, contains
-// a snapshot of the entire mapped memory space. Even a normal minidump,
-// with stack memory only, can be large if, for example, the dump was
-// generated in response to a crash that occurred due to an infinite-
-// recursion bug that caused the stack's limits to be exceeded. Finally,
-// some users of this library will unfortunately find themselves in the
-// position of having to process potentially-hostile minidumps that might
-// attempt to cause problems by forcing the minidump processor to over-
-// allocate memory.
-//
-// Memory management in this module is based on a strict
-// you-don't-own-anything policy. The only object owned by the user is
-// the top-level Minidump object, the creation and destruction of which
-// must be the user's own responsibility. All other objects obtained
-// through interaction with this module are ultimately owned by the
-// Minidump object, and will be freed upon the Minidump object's destruction.
-// Because memory regions can potentially involve large allocations, a
-// FreeMemory method is provided by MinidumpMemoryRegion, allowing the user
-// to release data when it is no longer needed. Use of this method is
-// optional but recommended. If freed data is later required, it will
-// be read back in from the minidump file again.
-//
-// There is one exception to this memory management policy:
-// Minidump::ReadString will return a string object to the user, and the user
-// is responsible for its deletion.
