FGETWS(3)                 (2019-03-06)                  FGETWS(3)

          fgetws - read a wide-character string from a FILE stream

          #include <wchar.h>

          wchar_t *fgetws(wchar_t *ws, int n, FILE *stream

          The fgetws() function is the wide-character equivalent of
          the fgets(3) function.  It reads a string of at most n-1
          wide characters into the wide-character array pointed to by
          ws, and adds a terminating null wide character (Laq\0aq).  It
          stops reading wide characters after it has encountered and
          stored a newline wide character.  It also stops when end of
          stream is reached.

          The programmer must ensure that there is room for at least n
          wide characters at ws.

          For a nonlocking counterpart, see unlocked_stdio(3).

          The fgetws() function, if successful, returns ws.  If end of
          stream was already reached or if an error occurred, it
          returns NULL.

          The behavior of fgetws() depends on the LC_CTYPE category of
          the current locale.

          In the absence of additional information passed to the
          fopen(3) call, it is reasonable to expect that fgetws() will
          actually read a multibyte string from the stream and then
          convert it to a wide-character string.

          This function is unreliable, because it does not permit to
          deal properly with null wide characters that may be present
          in the input.
