GETWC(3)	      DragonFly Library Functions Manual	      GETWC(3)

NAME

fgetwc, fgetwc_l, getwc, getwc_l, getwchar, getwchar_l -- get next wide character from input stream

LIBRARY

Standard C Library (libc, -lc)

SYNOPSIS

#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);

DESCRIPTION

The fgetwc() and fgetwc_l() functions obtain the next input wide charac- ter (if present) from the stream pointed at by stream, or the next char- acter pushed back on the stream via ungetwc(3) or ungetwc_l(3). The getwc() and getwc_l() functions act essentially identically to fgetwc() and fgetwc_l(). The getwchar() and getwchar_l() functions are equivalent to getwc() and getwc_l() with the argument stdin. The fgetwc_l(), getwc_l(), and getwchar_l() functions take an explicit locale argument, whereas the fgetwc(), getwc(), and getwchar() functions use the current global or per-thread locale.

RETURN VALUES

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 rou- tines 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 con- dition is remembered, even on a terminal, and all subsequent attempts to read will return WEOF until the condition is cleared with clearerr(3).
