-/**
- * _nm_utils_strsplit_set:
- * @str: string to split
- * @delimiters: string of delimiter characters
- * @max_tokens: the maximum number of tokens to split string into. When it is
- * less than 1, the @str is split completely.
- *
- * Utility function for splitting string into a string array. It is a wrapper
- * for g_strsplit_set(), but it also removes empty strings from the vector as
- * they are not useful in most cases.
- *
- * Returns: (transfer full): a newly allocated NULL-terminated array of strings.
- * The caller must free the returned array with g_strfreev().
