/* Assuming *OPTIONP is a comma separated list of elements of the form
   "token" or "token=value", getsubopt parses the first of these elements.
   If the first element refers to a "token" that is member of the given
   NULL-terminated array of tokens:
     - It replaces the comma with a NUL byte, updates *OPTIONP to point past
       the first option and the comma, sets *VALUEP to the value of the
       element (or NULL if it doesn't contain an "=" sign),
     - It returns the index of the "token" in the given array of tokens.
   Otherwise it returns -1, and *OPTIONP and *VALUEP are undefined.
   For more details see the POSIX:2001 specification.
