2367 * @ref_argv: pointer to the argv string vector variable that might be updated
2369 * This function parses the contents of the `MONO_ENV_OPTIONS`
2370 * environment variable as if they were parsed by a command shell
2371 * splitting the contents by spaces into different elements of the
2372 * @argv vector. This method supports quoting with both the " and '
2373 * characters. Inside quoting, spaces and tabs are significant,
2374 * otherwise, they are considered argument separators.
2376 * The \ character can be used to escape the next character which will
2377 * be added to the current element verbatim. Typically this is used
2378 * inside quotes. If the quotes are not balanced, this method
2380 * If the environment variable is empty, no changes are made
2381 * to the values pointed by @ref_argc and @ref_argv.
2383 * Otherwise the @ref_argv is modified to point to a new array that contains
2384 * all the previous elements contained in the vector, plus the values parsed.
2385 * The @argc is updated to match the new number of parameters.
2387 * Returns: The value NULL is returned on success, otherwise a g_strdup allocated
2388 * string is returned (this is an alias to malloc under normal circumstances) that
2389 * contains the error message that happened during parsing.
