o Reflect repo-copy of extattr.[c3] from libutil to libc, moving
extattr namespace routines to the libc/posix1e directory. While the extattr calls are not strictly POSIX.1e, POSIX.1e wasn't strictly ever approved, so I think that's OK. Obtained from: TrustedBSD Project

.Sh NAME

.Nm extattr_namespace_to_string ,
|
||||
.Nm extattr_string_to_namespace
|
||||
.Nd convert an extended attribute namespace identifier to a string and
|
||||
vice versa
|
||||
.Sh LIBRARY
|
||||
.Lb libutil
|
||||
.Sh SYNOPSIS
|
||||
.In sys/extattr.h
|
||||
.In libutil.h
|
||||
.Ft int
|
||||
.Fn extattr_namespace_to_string "int attrnamespace" "char **string"
|
||||
.Ft int
|
||||
.Fn extattr_string_to_namespace "const char *string" "int *attrnamespace"
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Fn extattr_namespace_to_string
|
||||
function converts a VFS extended attribute identifier to a human-readable
|
||||
string;
|
||||
the
|
||||
.Fn extattr_string_to_namespace
|
||||
function undoes the aforementioned operation,
|
||||
and converts a human-readable string representing a namespace to a
|
||||
namespace identifier.
|
||||
Although a filesystem may implement arbitrary namespaces,
|
||||
these functions only support the
|
||||
.Dv EXTATTR_NAMESPACE_USER
|
||||
.Pq Dq user
|
||||
and
|
||||
.Dv EXTATTR_NAMESPACE_SYSTEM
|
||||
.Pq Dq system
|
||||
namespaces,
|
||||
which are defined in
|
||||
.Xr extattr 9 .
|
||||
.Pp
|
||||
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 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 ERRORS
|
||||
.Bl -tag -width Er
|
||||
.It Bq Er EINVAL
|
||||
The requested namespace could not be identified.

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