# NAME

fputwc, putwc, putwchar, — output a wide character to a stream

# LIBRARY

Standard C Library (libc, -lc)

# SYNOPSIS

#include <stdio.h>
#include <wchar.h>
wint_t
fputwc(wchar_t wc, FILE *stream);
wint_t
putwc(wchar_t wc, FILE *stream);
wint_t
putwchar(wchar_t wc);

# DESCRIPTION

The fputwc() function writes the wide character wc to the output stream pointed to by stream.
putwc() acts essentially identically to fputwc(), but is a macro that expands in-line. It may evaluate stream more than once, so arguments given to putwc() should not be expressions with potential side effects.
putwchar() is identical to putwc() with an output stream of stdout.

# RETURN VALUES

The functions fputwc(), putwc(), and putwchar() return the wide character written. If an error occurs, the value `WEOF` is returned.

# SEE ALSO

ferror(3), fopen(3), getwc(3), stdio(3)

# STANDARDS

The functions fputwc(), putwc(), and putwchar(), conform to ISO/IEC 9899:1999 (“ISO C99”).
