GETWC(3)                NetBSD Library Functions Manual               GETWC(3)


NAME
fgetwc, getwc, getwchar -- 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();
DESCRIPTION
The fgetwc() function obtains 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). The getwc() function acts essentially identically to fgetwc(), but is a macro that expands in-line. The getwchar() function is equivalent to getwc() with the argument stdin.
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).
