2400 * splitting the contents by spaces into different elements of the
2401 * @argv vector. This method supports quoting with both the " and '
2402 * characters. Inside quoting, spaces and tabs are significant,
2403 * otherwise, they are considered argument separators.
2405 * The \ character can be used to escape the next character which will
2406 * be added to the current element verbatim. Typically this is used
2407 * inside quotes. If the quotes are not balanced, this method
2409 * If the environment variable is empty, no changes are made
2410 * to the values pointed by @ref_argc and @ref_argv.
2412 * Otherwise the @ref_argv is modified to point to a new array that contains
2413 * all the previous elements contained in the vector, plus the values parsed.
2414 * The @argc is updated to match the new number of parameters.
2416 * Returns: The value NULL is returned on success, otherwise a g_strdup allocated
2417 * string is returned (this is an alias to malloc under normal circumstances) that
2418 * contains the error message that happened during parsing.
