+ * <NAME>
+ * <FUNCTION DESCRIPTION>
+ *    The  wscanf_s  function  is  the  wide-character  equivalent  of the scanf_s function
+ *    The wscanf_s function reads data from the standard input stream stdin and
+ *    writes the data into the location that's given by argument. Each argument
+ *    must be a pointer to a variable of a type that corresponds to a type specifier
+ *    in format. If copying occurs between strings that overlap, the behavior is
+ *    undefined.
+ *
+ * <INPUT PARAMETERS>
+ *    format                  Format control string.
+ *    ...                         Optional arguments.
+ *
+ * <OUTPUT PARAMETERS>
+ *    ...                     the converted value stored in user assigned address
+ *
+ * <RETURN VALUE>
+ *    Returns the number of fields successfully converted and assigned;
+ *    the return value does not include fields that were read but not assigned.
+ *    A return value of 0 indicates that no fields were assigned.
+ *    return -1 if an error occurs.
