.TH PUTWCHAR 3 1999-07-25 "GNU" "Linux Programmer's Manual"
.SH NAME
putwchar \- write a wide character to standard output
.SH SYNOPSIS
.nf
.B #include <wchar.h>
.sp
.BI "wint_t putwchar(wchar_t " wc );
.fi
.SH DESCRIPTION
The
.BR putwchar ()
function is the wide-character equivalent of the
.BR putchar (3)
function.
It writes the wide character \fIwc\fP to \fIstdout\fP.
If \fIferror(stdout)\fP becomes true, it returns
.BR WEOF .
If a wide character
conversion error occurs, it sets \fIerrno\fP to \fBEILSEQ\fP and returns
.BR WEOF .
Otherwise it returns \fIwc\fP.
.PP
For a non-locking counterpart, see
.BR unlocked_stdio (3).
.SH "RETURN VALUE"
The
.BR putwchar ()
function returns \fIwc\fP if no error occurred, or
.B WEOF
to indicate an error.
.SH "CONFORMING TO"
C99.
.SH NOTES
The behavior of
.BR putwchar ()
depends on the
.B LC_CTYPE
category of the
current locale.
.PP
It is reasonable to expect that
.BR putwchar ()
will actually write
the multibyte sequence corresponding to the wide character \fIwc\fP.
.SH "SEE ALSO"
.BR fputwc (3),
.BR unlocked_stdio (3)
