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 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 .

ATTRIBUTES

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

STANDARDS

C11, POSIX.1-2008.

HISTORY

C99, POSIX.1-2001.

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.
