18 * <FUNCTION DESCRIPTION>
19 *   The  swprintf_s  function  is  the  wide-character  equivalent  of the sprintf_s function
20 *
21 * <INPUT PARAMETERS>
22 *    strDest                   Storage location for the output.
23 *    destMax                   Maximum number of characters to store.
24 *    format                    Format-control string.
25 *    ...                        Optional arguments
26 *
27 * <OUTPUT PARAMETERS>
28 *    strDest                    is updated
29 *
30 * <RETURN VALUE>
31 *    return  the number of wide characters stored in strDest, not  counting the terminating null wide character.
32 *    return -1  if an error occurred.
33 *
34 * If there is a runtime-constraint violation, strDest[0] will be set to the '\0' when strDest and destMax valid
