| .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 \fBputwchar\fP() function is the wide-character equivalent of the |
| \fBputchar\fP() function. 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 \fBerrno\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" |
| ISO/ANSI C, UNIX98 |
| .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. |
