+ * @brief Demangling routine.
+ * ABI-mandated entry point in the C++ runtime library for demangling.
+ *
+ * @param __mangled_name A NUL-terminated character string
+ * containing the name to be demangled.
+ *
+ * @param __output_buffer A region of memory, allocated with
+ * malloc, of @a *__length bytes, into which the demangled name is
+ * stored. If @a __output_buffer is not long enough, it is
+ * expanded using realloc. @a __output_buffer may instead be NULL;
+ * in that case, the demangled name is placed in a region of memory
+ * allocated with malloc.
+ *
+ * @param __length If @a __length is non-NULL, the length of the
+ * buffer containing the demangled name is placed in @a *__length.
+ *
+ * @param __status @a *__status is set to one of the following values:
+ * 0: The demangling operation succeeded.
+ * -1: A memory allocation failiure occurred.
+ * -2: @a mangled_name is not a valid name under the C++ ABI mangling rules.
+ * -3: One of the arguments is invalid.
+ *
+ * @return A pointer to the start of the NUL-terminated demangled
+ * name, or NULL if the demangling fails. The caller is
+ * responsible for deallocating this memory using @c free.
+ *
+ * The demangling is performed using the C++ ABI mangling rules,
+ * with GNU extensions. For example, this function is used in
+ * __gnu_cxx::__verbose_terminate_handler.
+ *
+ * See http://gcc.gnu.org/onlinedocs/libstdc++/manual/bk01pt12ch39.html
+ * for other examples of use.
+ *
+ * @note The same demangling functionality is available via
+ * libiberty (@c <libiberty/demangle.h> and @c libiberty.a) in GCC
+ * 3.1 and later, but that requires explicit installation (@c
+ * --enable-install-libiberty) and uses a different API, although
+ * the ABI is unchanged.

+ * @brief The cross-vendor C++ Application Binary Interface. A
+ * namespace alias to __cxxabiv1, but user programs should use the
+ * alias `abi'.
+ *
+ * A brief overview of an ABI is given in the libstdc++ FAQ, question
+ * 5.8 (you may have a copy of the FAQ locally, or you can view the online
+ * version at http://gcc.gnu.org/onlinedocs/libstdc++/faq/index.html#5_8).
+ *
+ * GCC subscribes to a cross-vendor ABI for C++, sometimes
+ * called the IA64 ABI because it happens to be the native ABI for that
+ * platform. It is summarized at http://www.codesourcery.com/cxx-abi/
+ * along with the current specification.
+ *
+ * For users of GCC greater than or equal to 3.x, entry points are
+ * available in <cxxabi.h>, which notes, <em>"It is not normally
+ * necessary for user programs to include this header, or use the
+ * entry points directly. However, this header is available should
+ * that be needed."</em>
