.Sh DESCRIPTION
The above functions scan input according to a specified
.Fa format
in the locale
.Fa loc .
They behave in the same way as the versions without the _l suffix, but use
the specific locale rather than the global or per-thread locale.
See the specific manual pages for more information.
.Sh SEE ALSO
.Xr scanf 3 ,
.Xr xlocale 3
.Sh STANDARDS
These functions do not conform to any specific standard so they should be
considered as non-portable local extensions.
.Sh HISTORY
These functions first appeared in Darwin and were first implemented in
.Fx 9.1
and
.Nx 7 .
