| .SH SYNOPSIS |
| .nf |

| .sp |
| .BI "wint_t towlower(wint_t " wc ); |
| .fi |
| .SH DESCRIPTION |
| The \fBtowlower\fP() function is the wide-character equivalent of the |
| \fBtolower\fP() function. 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. |
