NAME

6       fgetws - read a wide-character string from a FILE stream
7

SYNOPSIS

9       #include <wchar.h>
10
11       wchar_t *fgetws(wchar_t *ws, int n, FILE *stream);
12

DESCRIPTION

14       The  fgetws() function is the wide-character equivalent of the fgets(3)
15       function.  It reads a string of at most n-1 wide  characters  into  the
16       wide-character array pointed to by ws, and adds a terminating null wide
17       character (L'\0').  It stops  reading  wide  characters  after  it  has
18       encountered  and  stored  a newline wide character.  It also stops when
19       end of stream is reached.
20
21       The programmer must ensure that there is room for at least n wide char‐
22       acters at ws.
23
24       For a nonlocking counterpart, see unlocked_stdio(3).
25

RETURN VALUE

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

NOTES

43       The  behavior  of fgetws() depends on the LC_CTYPE category of the cur‐
44       rent locale.
45
46       In the absence of additional information passed to the  fopen(3)  call,
47       it is reasonable to expect that fgetws() will actually read a multibyte
48       string from the stream and then convert it to a wide-character string.
49
50       This function is unreliable, because it does not permit to  deal  prop‐
51       erly with null wide characters that may be present in the input.
