__cxa_demangle

char* abi::__cxa_demangle    (    const char *     mangled_name,    
char *     output_buffer,    
size_t *     length,    
int *     status    
)    
New ABI-mandated entry point in the C++ runtime library for demangling.
char* abi::__cxa_demangle(const char* mangled_name,                          char* output_buffer, size_t* length,                          int* status)

• 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.

• 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 failiure occurred. -2: mangled_name is not a valid name under the C++ ABI mangling rules. -3: One of the arguments is invalid.
