I think the current state is more than sufficient:

 * virStringSplit:
 * @string: a string to split
 * @delim: a string which specifies the places at which to split
 *     the string. The delimiter is not included in any of the resulting
 *     strings, unless @max_tokens is reached.
 * @max_tokens: the maximum number of pieces to split @string into.
 *     If this is 0, the string is split completely.
 * Splits a string into a maximum of @max_tokens pieces, using the given
 * @delim. If @max_tokens is reached, the remainder of @string is
 * appended to the last token.
 * As a special case, the result of splitting the empty string "" is an empty
 * vector, not a vector containing a single string. The reason for this
 * special case is that being able to represent a empty vector is typically
 * more useful than consistent handling of empty elements. If you do need
 * to represent empty elements, you'll need to check for the empty string
 * before calling virStringSplit().
 * Return value: a newly-allocated NULL-terminated array of strings. Use
 *    virStringFreeList() to free it.
char **virStringSplit(const char *string,
                      const char *delim,
                      size_t max_tokens)
