GETWC(3)

GETWC(3) | 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 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).

# STANDARDS

The `fgetwc`(), `getwc`() and `getwchar`() functions conform to ISO/IEC 9899:1999 (“ISO C99”) and IEEE Std 1003.1-2001 (“POSIX.1”).
