+.SH NAME
+getwchar \- read a wide character from standard input
+.SH LIBRARY
+Standard C library
+.RI ( libc ", " \-lc )
+.SH SYNOPSIS
+.nf
+.B #include <wchar.h>
+.P
+.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
+.I stdin
+and returns
+it.
+If the end of stream is reached, or if
+.I ferror(stdin)
+becomes true, it returns
+.BR WEOF .
+If a wide-character conversion error occurs, it sets
+.I errno
+to
+.B EILSEQ
+and returns
+.BR WEOF .
+.P
+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 ATTRIBUTES
+For an explanation of the terms used in this section, see
+.BR attributes (7).

+.SH STANDARDS

+.SH HISTORY
+C99, POSIX.1-2001.
+.SH NOTES
+The behavior of
+.BR getwchar ()
+depends on the
+.B LC_CTYPE
+category of the
+current locale.
+.P
+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.
