The Extended Attribute API
• Binds to the attribute trigger (using a binding from the attribute type’s schema entry)
• Makes the remote sec_attr_trig_update() call to the attribute trigger server,
passing in the attributes provided by the caller
• If the sec_attr_trig_update( ) call is successful, stores the output attribute(s) in the
registry database and returns the output attribute(s) to the caller
28.4.2 Trigger Binding
Two data types are used to defined an attribute trigger. The sec_attr_trig_type_t type
defines the type of attribute trigger. The sec_attr_bind_info_t data type, illustrated in
Figure 28-3 and described in this section, specifies the attribute trigger’s binding.

sec_attr_bind_auth_info_t, which defines the binding authentication and authorization
information.
