xattr_set — Set an extended attribute
This function sets the value of an extended attribute of a file.
Erweiterte Eigenschaften haben zwei
verschiedene Namensräume: den User- und den Root-Namensraum. Der
User-Namensraum steht allen Benutzern zur Verfügung, während der
Root-Namensraum nur Benutzern mit Root-Rechten zur Verfügung steht. xattr
operiert standardmäßig im User-Namensraum, aber das können Sie mit dem
Parameter flags ändern.
filenameThe file in which we set the attribute.
name
The name of the extended attribute. This attribute will be created if
it doesn't exist or replaced otherwise. You can change this behaviour
by using the flags parameter.
valueThe value of the attribute.
