This function sets value of an extended attribute named <parameter>name</parameter>
|
|
to <parameter>value</parameter> of a file <parameter>path</parameter>.
|
|
Extended attribute will be created if it doesn't exist or replaced
|
|
otherwise. You can change this behaviour by using <parameter>flags</parameter>
|
|
parameter.
|
|
</para>
|
|
<para>
|
|
Extended attributes have two different namespaces: user and root namespace.
|
|
User namespace is available for all users while root namespace is available
|
|
only for user with root privileges. xattr operates on user namespace by default,
|
|
but you can change that using <parameter>flags</parameter> argument.
