NAME

getwchar - read a wide character from standard input

LIBRARY

Standard C library (libc,~-lc)

SYNOPSIS

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

DESCRIPTION

The getwchar() function is the wid-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 wid-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 wid-character from standard input, or WEOF.

ATTRIBUTES

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

STANDARDS

HISTORY

C99, POSIX.-2001.

NOTES

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.
