3146 * mono_parse_env_options:
3147 * \param ref_argc pointer to the \c argc variable that might be updated
3148 * \param ref_argv pointer to the \c argv string vector variable that might be updated
3149 *
3150 * This function parses the contents of the \c MONO_ENV_OPTIONS
3151 * environment variable as if they were parsed by a command shell
3152 * splitting the contents by spaces into different elements of the
3153 * \p argv vector. This method supports quoting with both the " and '
3154 * characters. Inside quoting, spaces and tabs are significant,
3155 * otherwise, they are considered argument separators.
3156 *
3157 * The \ character can be used to escape the next character which will
3158 * be added to the current element verbatim. Typically this is used
3159 * inside quotes. If the quotes are not balanced, this method
3160 *
3161 * If the environment variable is empty, no changes are made
3162 * to the values pointed by \p ref_argc and \p ref_argv.
3163 *
3164 * Otherwise the \p ref_argv is modified to point to a new array that contains
3165 * all the previous elements contained in the vector, plus the values parsed.
3166 * The \p argc is updated to match the new number of parameters.
3167 *
3168 * If there is an error parsing, this method will terminate the process by
3169 * calling exit(1).
3170 *
3171 * An alternative to this method that allows an arbitrary string to be parsed
3172 * and does not exit on error is the `api:mono_parse_options_from`.
