2348 * Enable/disable crash chaining due to signals. When a fatal signal is delivered and
2349 * Mono doesn't know how to handle it, it will invoke the crash handler. If chrash chaining
2350 * is enabled, it will first print its crash information and then try to chain with the native handler.

2359 * mono_parse_options_from:
2360 * @options: string containing strings
2361 * @ref_argc: pointer to the argc variable that might be updated
2362 * @ref_argv: pointer to the argv string vector variable that might be updated
2364 * This function parses the contents of the `MONO_ENV_OPTIONS`
2365 * environment variable as if they were parsed by a command shell
2366 * splitting the contents by spaces into different elements of the
2367 * @argv vector. This method supports quoting with both the " and '
2368 * characters. Inside quoting, spaces and tabs are significant,
2369 * otherwise, they are considered argument separators.
2371 * The \ character can be used to escape the next character which will
2372 * be added to the current element verbatim. Typically this is used
2373 * inside quotes. If the quotes are not balanced, this method
2375 * If the environment variable is empty, no changes are made
2376 * to the values pointed by @ref_argc and @ref_argv.
2378 * Otherwise the @ref_argv is modified to point to a new array that contains
2379 * all the previous elements contained in the vector, plus the values parsed.
2380 * The @argc is updated to match the new number of parameters.
2382 * Returns: The value NULL is returned on success, otherwise a g_strdup allocated
2383 * string is returned (this is an alias to malloc under normal circumstances) that
2384 * contains the error message that happened during parsing.
