.SH NAME
getwchar \- read a wide character from standard input
.SH SYNOPSIS
.nf
.B #include <wchar.h>
.sp
.BI "wint_t getwchar(void);"
.fi
.SH DESCRIPTION
The \fBgetwchar\fP() function is the wide-character equivalent of the
2005-10-19 08:35:30 +00:00
\fBgetchar\fP() function. It reads a wide character from \fBstdin\fP and returns
2004-11-03 13:51:07 +00:00
it. If the end of stream is reached, or if \fIferror(stdin)\fP becomes
true, it returns WEOF. If a wide character conversion error occurs, it sets
2006-02-09 20:29:51 +00:00
\fIerrno\fP to \fBEILSEQ\fP and returns WEOF.

.PP
For a non-locking counterpart, see
.BR unlocked_stdio (3).
.SH "RETURN VALUE"
The \fBgetwchar\fP() function returns the next wide-character from
2004-11-03 13:51:07 +00:00
standard input, or WEOF.

.SH NOTES
The behaviour of \fBgetwchar\fP() depends on the LC_CTYPE category of the
2004-11-03 13:51:07 +00:00
current locale.
.PP
It is reasonable to expect that \fBgetwchar\fP() will actually read a multibyte
2004-11-03 13:51:07 +00:00
sequence from standard input and then convert it to a wide character.
