3148 *
3149 * This function parses the contents of the \c MONO_ENV_OPTIONS
3150 * environment variable as if they were parsed by a command shell
3151 * splitting the contents by spaces into different elements of the
3152 * \p argv vector. This method supports quoting with both the " and '
3153 * characters. Inside quoting, spaces and tabs are significant,
3154 * otherwise, they are considered argument separators.
3155 *
3156 * The \ character can be used to escape the next character which will
3157 * be added to the current element verbatim. Typically this is used
3158 * inside quotes. If the quotes are not balanced, this method
3159 *
3160 * If the environment variable is empty, no changes are made
3161 * to the values pointed by \p ref_argc and \p ref_argv.
3162 *
3163 * Otherwise the \p ref_argv is modified to point to a new array that contains
3164 * all the previous elements contained in the vector, plus the values parsed.
3165 * The \p argc is updated to match the new number of parameters.
3166 *
3167 * If there is an error parsing, this method will terminate the process by
3168 * calling exit(1).
3169 *
3170 * An alternative to this method that allows an arbitrary string to be parsed
3171 * and does not exit on error is the `api:mono_parse_options_from`.
