GETWCHAR(3) Linux Programmer s Manual GETWCHAR(3)
NAME getwchar - read a wide character from standard input
SYNOPSIS #include <wchar.h>
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 C99
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 multi- byte sequence from standard input and then convert it to a wide charac- ter.
