The data for configuring servers includes arrays of attributes. For flexibility, dced is implemented using the extensible and dynamic data structures developed for the DCE security registry attributes. This extended registry attribute (ERA) schema gives vendors the flexibility to modify the attributes appropriate for configuring servers on various systems. The use and modification of these data structures are described in The Extended Attribute API.
Applications commonly use dced_server_modify_attributes( ) after the dced_server_create( ) routine to change the default configuration attributes (the attributes field of a server_t structure) for a remote server. A dced_attr_list_t data structure is input that contains an array of sec_attr_t data structures and a count of the number in the array.
