fgetws - read a wide character string from a FILE stream
Návod, kniha: Linux Programmer's Manual
#include <wchar.h>
wchar_t *fgetws(wchar_t *ws, int n, FILE *stream);
The
fgetws function is the wide-character equivalent of the
fgets
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
characters at
ws.
For a non-locking 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.
ISO/ANSI C, UNIX98
The behaviour of
fgetws depends on the LC_CTYPE category of the current
locale.
In the absence of additional information passed to the fopen 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.
