NAME
fgetws - read a wide character string from a FILE streamSYNOPSIS
#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 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).
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 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.
