getwchar — read a wide character from standard input
#include <wchar.h>
wint_t getwchar( |
void) ; |
The getwchar
() function is
the wide-character equivalent of the getchar(3) function. It
reads a wide character from stdin
and returns it. If the end of stream
is reached, or if ferror(stdin)
becomes true,
it returns WEOF. If a wide-character conversion error occurs,
it sets errno
to EILSEQ and returns WEOF.
For a non-locking counterpart, see unlocked_stdio(3).
The behaviour of getwchar
()
depends on the LC_CTYPE category of the current locale.
It is reasonable to expect that getwchar
() will actually read a multibyte
sequence from standard input and then convert it to a wide
character.
