FGETWS(3) Linux Programmer's Manual 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 (L'\0').  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 char-
     acters 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 cur-
     rent 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 prop-
     erly with null wide characters that may be present in the input.
