GETWCHAR(3) Linux Programmer s Manual GETWCHAR(3)

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(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 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 behavior of getwchar() depends on the LC_CTYPE category of the cur- rent 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.
