/* This function takes a struct demangle_component tree and returns
   the corresponding demangled string.  The first argument is DMGL_*
   options.  The second is the tree to demangle.  The third is a guess
   at the length of the demangled string, used to initially allocate
   the return buffer.  The fourth is a pointer to a size_t.  On
   success, this function returns a buffer allocated by malloc(), and
   sets the size_t pointed to by the fourth argument to the size of
   the allocated buffer (not the length of the returned string).  On
   failure, this function returns NULL, and sets the size_t pointed to
   by the fourth argument to 0 for an invalid tree, or to 1 for a
   memory allocation error.  */

/* This function takes a struct demangle_component tree and passes back
   a demangled string in one or more calls to a callback function.
   The first argument is DMGL_* options.  The second is the tree to
   demangle.  The third is a pointer to a callback function; on each call
   this receives an element of the demangled string, its length, and an
   opaque value.  The fourth is the opaque value passed to the callback.
   The callback is called once or more to return the full demangled
   string.  The demangled element string is always nul-terminated, though
   its length is also provided for convenience.  In contrast to
   cplus_demangle_print(), this function does not allocate heap memory
   to grow output strings (except perhaps where alloca() is implemented
   by malloc()), and so is normally safe for use where the heap has been
   corrupted.  On success, this function returns 1; on failure, 0.  */
