.Sh DESCRIPTION
|
|
.Fn extattr_copy_file
|
|
copies extended attributes of namespace
|
|
.Ar namespace
|
|
from a file to another one.
|
|
.Fn extattr_copy_fd
|
|
does the same using open file descriptors, and
|
|
.Fn extattr_copy_link
|
|
does the same as
|
|
.Fn extattr_copy_file
|
|
but operates on symbolic links themselves instead of their targets.
|
|
.Pp
|
|
.Fn cpxattr ,
|
|
.Fn fcpxattr ,
|
|
and
|
|
.Fn lcpxattr
|
|
respectively work the same was as
|
|
.Fn extattr_copy_file ,
|
|
.Fn extattr_copy_fd ,
|
|
and
|
|
.Fn extattr_copy_link ,
|
|
but will copy extended attributes from all namespaces accessible to the user,
|
|
silently skiping unaccessible namespaces.
|
|
.Pp
|
|
Please note that none of the extended attribute copying functions are atomic.
|
|
.Sh RETURN VALUES
|
|
If any of the calls are unsuccessful, the value \-1 is returned
|
|
and the global variable
|
|
.Va errno
|
|
is set to indicate the error.
|
|

.Sh HISTORY
|
|
Extended attribute support was developed as part of the
|
|
.Tn TrustedBSD
|
|
Project, and introduced in
|
|
.Fx 5.0
|
|
and
|
|
.Nx 3.0 .
|
|
It was developed to support security extensions requiring additional labels
|
|
to be associated with each file or directory.
