- * <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.
