NAME


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

 

SYNOPSIS


       #include 

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

 

DESCRIPTION






       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 L'\0'
       character.  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 non-locking counterpart, see unlocked_stdio(3).

 

RETURN VALUE


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

 

CONFORMING TO


       C99, POSIX.1-2001.

 

NOTES


       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.
