.Dd October 3, 2002 .Dt TOWLOWER 3 .Os .Sh NAME .Nm towlower , .Nm towlower_l .Nd "upper case to lower case letter conversion (wide character version)" .Sh LIBRARY .Lb libc .Sh SYNOPSIS n wctype.h .Ft wint_t .Fo towlower .Fa "wint_t wc" .Fc n wctype.h n xlocale.h .Ft wint_t .Fo towlower_l .Fa "wint_t wc" .Fa "locale_t loc" .Fc .Sh DESCRIPTION The .Fn towlower function converts an upper-case letter to the corresponding lower-case letter.
p Although the .Fn towlower function uses the current locale, the .Fn towlower_l function may be passed a locale directly. See .Xr xlocale 3 for more information. .Sh RETURN VALUES If the argument is an upper-case letter, the .Fn towlower function returns the corresponding lower-case letter if there is one; otherwise, the argument is returned unchanged. .Sh SEE ALSO .Xr iswlower 3 , .Xr tolower 3 , .Xr towupper 3 , .Xr wctrans 3 , .Xr xlocale 3 .Sh STANDARDS The .Fn towlower function conforms to .St -isoC-99 .
