Description

   The fgetws function reads wide characters from the specified file
   and stores them in the array pointed to by wstr. The function
   reads up to maxchar-1 characters or until the new-line character
   is read, converted, and transferred to wstr, or until an end-
   of-file condition is encountered. The function terminates the
   line with a null wide character. fgetws places the new-line that
   terminates the input line into the user buffer, unless maxchar
   characters have already been fetched.
