* <FUNCTION DESCRIPTION>
|
|
* The swprintf_s function is the wide-character equivalent of the sprintf_s function
|
|
*
|
|
* <INPUT PARAMETERS>
|
|
* strDest Storage location for the output.
|
|
* destMax Maximum number of characters to store.
|
|
* format Format-control string.
|
|
* ... Optional arguments
|
|
*
|
|
* <OUTPUT PARAMETERS>
|
|
* strDest is updated
|
|
*
|
|
* <RETURN VALUE>
|
|
* return the number of wide characters stored in strDest, not counting the terminating null wide character.
|
|
* return -1 if an error occurred.
|
|
*
|
|
* If there is a runtime-constraint violation, strDest[0] will be set to the '\0' when strDest and destMax valid
