If \fIwc\fP is a wide character, it is converted to +lowercase. Characters which do not have case are returned unchanged. +If \fIwc\fP is WEOF, WEOF is returned. +.SH "RETURN VALUE" +The \fBtowlower\fP function returns the lowercase equivalent of \fIwc\fP, +or WEOF if \fIwc\fP is WEOF. +.SH "CONFORMING TO" +ISO/ANSI C, UNIX98 +.SH "SEE ALSO" +.BR iswlower (3), +.BR towctrans (3), +.BR towupper (3) +.SH NOTES +The behaviour of \fBtowlower\fP depends on the LC_CTYPE category of the +current locale. +.PP +This function is not very appropriate for dealing with Unicode characters, +because Unicode knows about three cases: upper, lower and title case. |
