+/* 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. */
