-/* Write formatted output to a string dynamically allocated with malloc().
-   You can pass a preallocated buffer for the result in RESULTBUF and its
-   size in *LENGTHP; otherwise you pass RESULTBUF = NULL.
-   If successful, return the address of the string (this may be = RESULTBUF
-   if no dynamic memory allocation was necessary) and set *LENGTHP to the
-   number of resulting bytes, excluding the trailing NUL.  Upon error, set
-   errno and return NULL.
-
-   When dynamic memory allocation occurs, the preallocated buffer is left
-   alone (with possibly modified contents).  This makes it possible to use
-   a statically allocated or stack-allocated buffer, like this:
-
-          char buf[100];
-          size_t len = sizeof (buf);
-          char *output = vasnprintf (buf, &len, format, args);
-          if (output == NULL)
-            ... error handling ...;
-          else
-            {
-              ... use the output string ...;
-              if (output != buf)
-                free (output);
-            }
