getwchar(3) -- Linux man page

 

NAME

getwchar - read a wide character from standard input  

SYNOPSIS

#include <wchar.h>

wint_t getwchar(void);
 

DESCRIPTION

The getwchar function is the wide-character equivalent of the getchar 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 non-locking counterpart, see unlocked_stdio(3).  

RETURN VALUE

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

CONFORMING TO

ISO/ANSI C, UNIX98  

NOTES

The behaviour 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.
