| 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 | |
| 60a90ecd MK |
25 | The |
| 26 | .BR putwchar () | |
| 27 | function is the wide-character equivalent of the | |
| 28 | .BR putchar (3) | |
| 29 | function. | |
| 9bef72b5 | 30 | It writes the wide character \fIwc\fP to \fIstdout\fP. |
| cab87712 MK |
31 | If \fIferror(stdout)\fP becomes true, it returns |
| 32 | .BR WEOF . | |
| c13182ef | 33 | If a wide character |
| cab87712 MK |
34 | conversion error occurs, it sets \fIerrno\fP to \fBEILSEQ\fP and returns |
| 35 | .BR WEOF . | |
| fea681da MK |
36 | Otherwise it returns \fIwc\fP. |
| 37 | .PP | |
| 24b74457 | 38 | For a nonlocking counterpart, see |
| fea681da MK |
39 | .BR unlocked_stdio (3). |
| 40 | .SH "RETURN VALUE" | |
| 60a90ecd MK |
41 | The |
| 42 | .BR putwchar () | |
| cab87712 MK |
43 | function returns \fIwc\fP if no error occurred, or |
| 44 | .B WEOF | |
| 45 | to indicate an error. | |
| fea681da | 46 | .SH "CONFORMING TO" |
| 68e1685c | 47 | C99. |
| fea681da | 48 | .SH NOTES |
| d9bfdb9c | 49 | The behavior of |
| 60a90ecd | 50 | .BR putwchar () |
| 1274071a MK |
51 | depends on the |
| 52 | .B LC_CTYPE | |
| 53 | category of the | |
| fea681da MK |
54 | current locale. |
| 55 | .PP | |
| 60a90ecd MK |
56 | It is reasonable to expect that |
| 57 | .BR putwchar () | |
| 58 | will actually write | |
| fea681da MK |
59 | the multibyte sequence corresponding to the wide character \fIwc\fP. |
