NAMEgetwchar − read a wide character from standard input

---

LIBRARYStandard C library (libc, −lc)

---

SYNOPSIS#include <wchar.h>wint_t getwchar(void);"

---

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

---

ATTRIBUTESFor an explanation of the terms used in this section, see attributes(7). InterfaceAttributeValue getwchar() Thread safetyMT-Safe

---

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

---

NOTESThe 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.
