char* __cxa_demangle	(	const char *	__mangled_name,
		char *	__output_buffer,
		size_t *	__length,
		int *	__status
	)

Demangling routine.

ABI-mandated entry point in the C++ runtime library for demangling.

Parameters

__mangled_name	A NUL-terminated character string containing the name to be demangled.
__output_buffer	A region of memory, allocated with malloc, of *__length bytes, into which the demangled name is stored. If __output_buffer is not long enough, it is expanded using realloc. __output_buffer may instead be NULL; in that case, the demangled name is placed in a region of memory allocated with malloc.
__length	If __length is non-NULL, the length of the buffer containing the demangled name is placed in *__length.
__status	*__status is set to one of the following values: 0: The demangling operation succeeded. -1: A memory allocation failure occurred. -2: mangled_name is not a valid name under the C++ ABI mangling rules. -3: One of the arguments is invalid.

Returns

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 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 (<libiberty/demangle.h> and libiberty.a) in GCC 3.1 and later, but that requires explicit installation (–enable-install-libiberty) and uses a different API, although the ABI is unchanged.
