| .TH PUTWCHAR 3 1999-07-25 "GNU" "Linux Programmer's Manual" |
| .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 |
| .BR putwchar () |
| function is the wide-character equivalent of the |
| .BR putchar (3) |
| function. |
| It writes the wide character \fIwc\fP to \fIstdout\fP. |
| If \fIferror(stdout)\fP becomes true, it returns |
| .BR WEOF . |
| If a wide character |
| conversion error occurs, it sets \fIerrno\fP to \fBEILSEQ\fP and returns |
| .BR WEOF . |
| Otherwise it returns \fIwc\fP. |
| .PP |
| For a nonlocking counterpart, see |
| .BR unlocked_stdio (3). |
| .SH "RETURN VALUE" |
| The |
| .BR putwchar () |
| function returns \fIwc\fP if no error occurred, or |
| .B WEOF |
| to indicate an error. |
| .SH "CONFORMING TO" |
| C99. |
| .SH NOTES |
| The behavior of |
| .BR putwchar () |
| depends on the |
| .B LC_CTYPE |
| category of the |
| current locale. |
| .PP |
| It is reasonable to expect that |
| .BR putwchar () |
| will actually write |
| the multibyte sequence corresponding to the wide character \fIwc\fP. |
| .SH "SEE ALSO" |
| .BR fputwc (3), |
| .BR unlocked_stdio (3) |
