xattr_set — Set an extended attribute
This function sets the value of an extended attribute of a file.
Rozšírené atribúty majú dve odlišné namespacey: user a root namespace. User namespace je dostupná pre všetkých užívateľov, zatiaľčo root namespace je dostupná iba pre užívateľa s rootovskými privilégiami. xattr ako default pracuje na user namespace, ale môžete to zmeniť pomocou argumentu flags .
