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