- * <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.
