.Sh DESCRIPTION
|
|
|
|
The above functions perform character tests and conversions on the integer
|
2012-03-29 05:02:12 +00:00
|
|
|
.Fa c
|
2012-03-13 20:02:41 +00:00
|
|
|
in the locale
|
|
|
|
.Fa loc .
|
|
|
|
They behave in the same way as the versions without the _l suffix, but use the
|
2012-03-29 05:02:12 +00:00
|
|
|
specified locale rather than the global or per-thread locale.
|
2012-03-13 20:02:41 +00:00
|
|
|
.In ctype.h ,
|
|
|
|
or as true functions in the C library.
