It writes the wide character \fIwc\fP to \fBstdout\fP. If \fIferror(stdout)\fP becomes true, it returns WEOF. If a wide character conversion error occurs, it sets \fIerrno\fP to \fBEILSEQ\fP and returns WEOF. Otherwise it returns \fIwc\fP. .PP For a non-locking counterpart, see .BR unlocked_stdio (3). .SH "RETURN VALUE" The \fBputwchar\fP() function returns \fIwc\fP if no error occurred, or WEOF to indicate an error. .SH "CONFORMING TO" C99. .SH NOTES The behaviour of \fBputwchar\fP() depends on the LC_CTYPE category of the current locale. .PP It is reasonable to expect that \fBputwchar\fP() will actually write the multibyte sequence corresponding to the wide character \fIwc\fP. .SH "SEE ALSO" .BR fputwc (3), .BR unlocked_stdio (3)
