*int fwscanf(stream, format, ...) - read formatted data from stream

* Reads formatted data from stream into arguments. _input does the real

*
*Entry:
* FILE *stream - stream to read data from
* wchar_t *format - format string
* followed by list of pointers to storage for the data read. The number
* and type are controlled by the format string.
*
*Exit:
* returns number of fields read and assigned
