DESCRIPTION
The above functions perform character tests and conversions on the
integer c in the locale loc. 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. <ctype.h>, or as true functions in the C
library. See the specific manual pages for more information.
