.Sh SYNOPSIS
|
|
.In stdio.h
|
|
.In wchar.h
|
|
.Ft wint_t
|
|
.Fn fputwc "wchar_t wc" "FILE *stream"

.Fn putwc "wchar_t wc" "FILE *stream"

.Fn putwchar "wchar_t wc"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn fputwc
|
|
function
|
|
writes the wide character
|
|
.Fa wc
|
|
to the output stream pointed to by
|
|
.Fa stream .
|
|
.Pp
|
|
.Fn putwc
|
|
acts essentially identically to
|
|
.Fn fputwc ,
|
|
but is a macro that expands in-line.
|
|
It may evaluate
|
|
.Fa stream
|
|
more than once, so arguments given to
|
|
.Fn putwc
|
|
should not be expressions with potential side effects.
|
|
.Pp
|
|
.Fn putwchar
|
|
is identical to
|
|
.Fn putwc
|
|
with an output stream of
|
|
.Em stdout .
|
|
.Sh RETURN VALUES
|
|
The functions
|
|
.Fn fputwc ,
|
|
.Fn putwc ,
|
|
and
|
|
.Fn putwchar
|
|
return the wide character written.
|
|
If an error occurs, the value
|
|
.Dv WEOF
|
|
is returned.
