The
.Fn extattr_namespace_to_string
function converts a VFS extended attribute identifier to a human-readable
string.
The
.Fn extattr_string_to_namespace
converts a human-readable string representing a namespace to a
namespace identifier.
Although a file system may implement arbitrary namespaces,
these functions only support the

.Dv EXTATTR_NAMESPACE_SYSTEM

namespaces,
which are defined in

These functions are meant to be used in error reporting and other
interactive tasks.
For example,
instead of printing the integer identifying an extended attribute in
an error message,
a program might use
.Fn extattr_namespace_to_string
to obtain a human-readable representation.
Likewise,
instead of requiring a user to enter the integer representing a namespace,
an interactive program might ask for a name and use
.Fn extattr_string_to_namespace
to get the desired identifier.

.Sh HISTORY
Extended attribute support was developed as part of the

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.
