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 nonlocking counterpart, see unlocked_stdio(3).

Return Value

The getwchar() function returns the next wide-character from standard input, or WEOF.


For an explanation of the terms used in this section, see attributes(7).

Conforming to

POSIX.1-2001, POSIX.1-2008, C99.


The behavior 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.
