GETWC(3) Library Functions Manual GETWC(3)

fgetwc, fgetwc_l, getwc, getwc_l, getwchar, getwchar_lget next wide character from input stream

library “libc”

#include <stdio.h>
#include <wchar.h>

wint_t
fgetwc(FILE *stream);

wint_t
getwc(FILE *stream);

wint_t
getwchar(void);

#include <xlocale.h>

wint_t
fgetwc_l(FILE *stream, locale_t locale);

wint_t
getwc_l(FILE *stream, locale_t locale);

wint_t
getwchar_l(locale_t locale);

The () and fgetwc_l() functions obtain the next input wide character (if present) from the stream pointed at by stream, or the next character pushed back on the stream via ungetwc(3) or ungetwc_l(3).

The () and () functions act essentially identically to fgetwc() and fgetwc_l().

The () and () functions are equivalent to getwc() and getwc_l() with the argument stdin.

The (), (), and getwchar_l() functions take an explicit locale argument, whereas the fgetwc(), getwc(), and getwchar() functions use the current global or per-thread locale.

If successful, these routines return the next wide character from the stream. If the stream is at end-of-file or a read error occurs, the routines return WEOF. The routines feof(3) and ferror(3) must be used to distinguish between end-of-file and error. If an error occurs, the global variable errno is set to indicate the error. The end-of-file condition is remembered, even on a terminal, and all subsequent attempts to read will return WEOF until the condition is cleared with clearerr(3).

The fgetwc(), getwc() and getwchar() functions conform to ISO/IEC 9899:1999 (“ISO C99”).
