.TH GETWCHAR 3 1999-07-25 "GNU" "Linux Programmer's Manual"
|
|
.SH NAME
|
|
getwchar \- read a wide character from standard input
|
|
.SH SYNOPSIS
|
|
.nf
|
|
.B #include <wchar.h>
|
|
.sp
|
|
.B "wint_t getwchar(void);"
|
|
.fi
|
|
.SH DESCRIPTION
|
|
The
|
|
.BR getwchar ()
|
|
function is the wide-character equivalent of the
|
|
.BR getchar (3)
|
|
function.
|
|
It reads a wide character from \fIstdin\fP and returns
|
|
it.
|
|
If the end of stream is reached, or if \fIferror(stdin)\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 .
|
|
.PP
|
|
For a nonlocking counterpart, see
|
|
.BR unlocked_stdio (3).
|
|
.SH "RETURN VALUE"
|
|
The
|
|
.BR getwchar ()
|
|
function returns the next wide-character from
|
|
standard input, or
|
|
.BR WEOF .
|
|
.SH "CONFORMING TO"
|
|
C99.
|
|
.SH NOTES
|
|
The behavior of
|
|
.BR getwchar ()
|
|
depends on the
|
|
.B LC_CTYPE
|
|
category of the
|
|
current locale.
|
|
.PP
|
|
It is reasonable to expect that
|
|
.BR getwchar ()
|
|
will actually
|
|
read a multibyte sequence from standard input and then
|
|
convert it to a wide character.
