This function removes an extended attribute named <parameter>name</parameter>

of a file <parameter>path</parameter>.

<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.
