17 Extended attributes are name:value pairs associated with inodes (files,
18 directories, symlinks, etc). They are extensions to the normal
19 attributes which are associated with all inodes in the system (i.e. the
20 stat(2) data). A complete overview of extended attributes concepts can
21 be found in attr(5).
22
23 removexattr removes the extended attribute identified by name and asso‐
24 ciated with the given path in the filesystem.
25
26 lremovexattr is identical to removexattr, except in the case of a sym‐
27 bolic link, where the extended attribute is removed from the link
28 itself, not the file that it refers to.
29
30 fremovexattr is identical to removexattr, only the extended attribute
31 is removed from the open file pointed to by filedes (as returned by
32 open(2)) in place of path.
33
34 An extended attribute name is a simple NULL-terminated string. The
35 name includes a namespace prefix - there may be several, disjoint
36 namespaces associated with an individual inode.
37
39 On success, zero is returned. On failure, -1 is returned and errno is
40 set appropriately.
41
42 If the named attribute does not exist, errno is set to ENOATTR.
43
44 If extended attributes are not supported by the filesystem, or are dis‐
45 abled, errno is set to ENOTSUP.
46
47 The errors documented for the stat(2) system call are also applicable
48 here.
