They behave in the same way as the versions without the _l suffix, but use the specified locale rather than the global or per-thread locale. These functions may be implemented as inline functions in .In wctype.h and as functions in the C library. See the specific manual pages for more information. .Sh RETURN VALUES These functions return the same things as their non-locale versions. If the locale is invalid, their behaviors are undefined. .Sh SEE ALSO .Xr iswalnum 3 , .Xr iswalpha 3 , .Xr iswblank 3 , .Xr iswcntrl 3 , .Xr iswctype 3 , .Xr iswdigit 3 , .Xr iswgraph 3 , .Xr iswhexnumber 3 , .Xr iswideogram 3 , .Xr iswlower 3 , .Xr iswnumber 3 , .Xr iswphonogram 3 , .Xr iswprint 3 , .Xr iswpunct 3 , .Xr iswrune 3 , .Xr iswspace 3 , .Xr iswspecial 3 , .Xr iswupper 3 , .Xr iswxdigit 3 , .Xr nextwctype 3 , .Xr towctrans 3 , .Xr towlower 3 , .Xr towupper 3 , .Xr wctrans 3 , .Xr wctype 3 .Sh STANDARDS These functions conform to .St -p1003.1-2008 , except for .Fn iswascii_l , .Fn iswhexnumber_l , .Fn iswideogram_l , .Fn iswphonogram_l , .Fn iswrune_l , .Fn iswspecial_l and .Fn nextwctype_l which are .Fx extensions.
