Enumeration Type Documentation

enum Eina_Xattr_Flags

define extended attribute creation

Since (EFL) :
1.1
Enumerator:
EINA_XATTR_INSERT 

This is the default behaviour, it will either create or replace the extended attribute

EINA_XATTR_REPLACE 

This will only succeed if the extended attribute previously existed

EINA_XATTR_CREATED 

This will only succeed if the extended attribute wasn't previously set
