54 .\"O Extended attributes are
56 .\"O value pairs associated with inodes (files, directories, symbolic links, etc.).
57 .\"O They are extensions to the normal attributes which are associated
58 .\"O with all inodes in the system (i.e., the

92 .\"O removed from the link itself, not the file that it refers to.

121 .\"O An extended attribute name is a simple null-terminated string.
124 .\"O includes a namespace prefix; there may be several, disjoint
125 .\"O namespaces associated with an individual inode.
126 拡張属性の名前は、普通の NULL 終端された文字列である。

132 .\"O On success, zero is returned.
133 .\"O On failure, \-1 is returned and
135 .\"O is set appropriately.

151 .\"O If extended attributes are not supported by the file system, or are disabled,
