Example: - * - * <!--#exec "ls -l" --> - * - * The call directive is a way to invoke a C handler from the HTML page. - * On each occurence of <!--#call COMMAND OPTIONAL_PARAMS> directive, - * Mongoose calls a registered event handler with MG_EV_SSI_CALL event, - * and event parameter will point to the COMMAND OPTIONAL_PARAMS string. - * An event handler can output any text, for example by calling - * `mg_printf()`.
