property_add() callback

Called when a client adds a new property to a node

Synopsis:

#include <sys/pmm.h>

int property_add(void *data, pm_property_attr_t *prop, 
                                           void *val);

libc

This function is called when a client adds a new property to a node:

data

Policy specific data returned by the create() function when the node was created.

prop

Describes the property:

val

Initial property data set by the client.

The return value from this call indicates whether the property can be attached:

if this returns EOK, the property is allowed, and this call allows the policy to detect when new properties are added.
if this returns an error, that error code is passed back to the client's pm_add_property() call, and the property is not attached to the node.

The default action (if the policy does not override this function) is to allow any property to be added.
