/* Searches the next delimiter (char listed in DELIM) starting at *STRINGP.
   If one is found, it is overwritten with a NUL, and *STRINGP is advanced
   to point to the next char after it.  Otherwise, *STRINGP is set to NULL.
   If *STRINGP was already NULL, nothing happens.
   Returns the old value of *STRINGP.

   This is a variant of strtok() that is multithread-safe and supports
   empty fields.

   Caveat: It modifies the original string.
   Caveat: These functions cannot be used on constant strings.
   Caveat: The identity of the delimiting character is lost.
   Caveat: It doesn't work with multibyte strings unless all of the delimiter
           characters are ASCII characters < 0x30.

   See also strtok_r().  */
