getwchar(3) Library Functions Manual getwchar(3)
NAME top
getwchar - read a wide character from standard input
LIBRARY top
Standard C library (_libc_, _-lc_)
SYNOPSIS top
**#include <wchar.h>**
**wint_t getwchar(void);**
DESCRIPTION top
The **getwchar**() function is the wide-character equivalent of the
[getchar(3)](../man3/getchar.3.html) 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](../man3/errno.3.html)_ to **EILSEQ** and returns **WEOF**.
For a nonlocking counterpart, see [unlocked_stdio(3)](../man3/unlocked%5Fstdio.3.html).
RETURN VALUE top
The **getwchar**() function returns the next wide-character from
standard input, or **WEOF**.

HISTORY top
C99, POSIX.1-2001.
NOTES top
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.
