+ * <FUNCTION DESCRIPTION>
+ *    The fwscanf_s function  is  the  wide-character  equivalent  of the fscanf_s function
+ *    The fwscanf_s function reads data from the current position of stream into
+ *    the locations given by argument (if any). Each argument must be a pointer
+ *    to a variable of a type that corresponds to a type specifier in format.
+ *    format controls the interpretation of the input fields and has the same
+ *    form and function as the format argument for scanf.
+ *
+ * <INPUT PARAMETERS>
+ *    stream                   Pointer to FILE structure.
+ *    format                   Format control string, see Format Specifications.
+ *    ...                      Optional arguments.
+ *
+ * <OUTPUT PARAMETERS>
+ *    ...                      The converted value stored in user assigned address
+ *
+ * <RETURN VALUE>
+ *    Each of these functions 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.
