.SH DESCRIPTION
|
2007-05-12 09:06:04 +00:00
|
|
|
The
|
|
|
|
|
.BR fputwc ()
|
|
|
|
|
function is the wide-character
|
|
|
|
|
equivalent of the
|
2007-05-21 17:50:05 +00:00
|
|
|
.BR fputc (3)
|
2007-05-12 09:06:04 +00:00
|
|
|
function.
|
2007-04-12 22:42:49 +00:00
|
|
|
It writes the wide character \fIwc\fP to \fIstream\fP.
|
|
|
|
|
If
|
2007-07-09 20:43:38 +00:00
|
|
|
\fIferror(stream)\fP becomes true, it returns
|
|
|
|
|
.BR WEOF .
|
2007-04-24 19:40:35 +00:00
|
|
|
If a wide-character conversion error occurs,
|
2007-07-09 20:43:38 +00:00
|
|
|
it sets \fIerrno\fP to \fBEILSEQ\fP and returns
|
|
|
|
|
.BR WEOF .
|
2004-11-03 13:51:07 +00:00
|
|
|
Otherwise it returns \fIwc\fP.

The tendency in English, as prescribed in style guides like
Chicago MoS, is towards removing hyphens after prefixes
like "non-" etc.
