About the attr_changed entry point

This entry point provides a way to respond to resource attribute value changes. The attr_changed entry point is called when a resource attribute is modified, and only if that resource attribute is registered with the agent framework for notification.

See VCSAgRegister.

See VCSAgUnregister.

You can also register resource attributes using the RegList attribute.

See RegList.

The attr_changed entry point receives as input the resource name registered with the agent framework for notification, the name of the changed resource, the name of the changed attribute, and the new attribute value. It does not return a value.
