.SH DESCRIPTION
|
2005-10-19 06:54:38 +00:00
|
|
|
The \fBputwchar\fP() function is the wide-character equivalent of the
|
2005-10-19 08:35:30 +00:00
|
|
|
\fBputchar\fP() function. It writes the wide character \fIwc\fP to \fBstdout\fP.
|
2004-11-03 13:51:07 +00:00
|
|
|
If \fIferror(stdout)\fP becomes true, it returns WEOF. If a wide character
|
2006-02-09 20:29:51 +00:00
|
|
|
conversion error occurs, it sets \fIerrno\fP to \fBEILSEQ\fP and returns WEOF.
|
2004-11-03 13:51:07 +00:00
|
|
|
Otherwise it returns \fIwc\fP.

.SH "RETURN VALUE"
|
2005-10-19 06:54:38 +00:00
|
|
|
The \fBputwchar\fP() function returns \fIwc\fP if no error occurred, or WEOF to
|
2004-11-03 13:51:07 +00:00
|
|
|
indicate an error.

.SH NOTES
|
2005-10-19 06:54:38 +00:00
|
|
|
The behaviour of \fBputwchar\fP() depends on the LC_CTYPE category of the
|
2004-11-03 13:51:07 +00:00
|
|
|
current locale.
|
|
|
|
.PP
|
2005-10-19 06:54:38 +00:00
|
|
|
It is reasonable to expect that \fBputwchar\fP() will actually write
|
2004-11-03 13:51:07 +00:00
|
|
|
the multibyte sequence corresponding to the wide character \fIwc\fP.
