fgetws - read a wide character string from a FILE stream
SYNOPSIS
#include <wchar.h>
wchar_t *fgetws (wchar_t *ws, int n, FILE *stream);
DESCRIPTION
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 new
line 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.
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
ISO/ANSI C, UNIX98
SEE ALSO
fgetwc(3)
NOTES
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 pre
sent in the input.
