| 15 | .TH PUTWCHAR 3 1999-07-25 "GNU" "Linux Programmer's Manual" | |
| 16 | .SH NAME | |
| 17 | putwchar \- write a wide character to standard output | |
| 18 | .SH SYNOPSIS | |
| 19 | .nf | |
| 20 | .B #include <wchar.h> | |
| 21 | .sp | |
| 22 | .BI "wint_t putwchar(wchar_t " wc ); | |
| 23 | .fi | |
| 24 | .SH DESCRIPTION | |
| e511ffb6 | 25 | The \fBputwchar\fP() function is the wide-character equivalent of the |
| 3382bd94 | 26 | \fBputchar\fP() function. It writes the wide character \fIwc\fP to \fBstdout\fP. |
| fea681da | 27 | If \fIferror(stdout)\fP becomes true, it returns WEOF. If a wide character |
| dcec8eb5 | 28 | conversion error occurs, it sets \fIerrno\fP to \fBEILSEQ\fP and returns WEOF. |
| fea681da MK |
29 | Otherwise it returns \fIwc\fP. |
| 30 | .PP | |
| 31 | For a non-locking counterpart, see | |
| 32 | .BR unlocked_stdio (3). | |
| 33 | .SH "RETURN VALUE" | |
| e511ffb6 | 34 | The \fBputwchar\fP() function returns \fIwc\fP if no error occurred, or WEOF to |
| fea681da MK |
35 | indicate an error. |
| 36 | .SH "CONFORMING TO" | |
| 37 | ISO/ANSI C, UNIX98 | |
| 38 | .SH NOTES | |
| e511ffb6 | 39 | The behaviour of \fBputwchar\fP() depends on the LC_CTYPE category of the |
| fea681da MK |
40 | current locale. |
| 41 | .PP | |
| e511ffb6 | 42 | It is reasonable to expect that \fBputwchar\fP() will actually write |
| fea681da MK |
43 | the multibyte sequence corresponding to the wide character \fIwc\fP. |
