DESCRIPTION

The ptree_update_propval() function updates the value of the property specified by proph with the value specified in the buffer valbuf. The size of the buffer valbuf is specified in nbytes.

The ptree_update_propval_by_name() function updates the value of the property, whose name is specified by name, of the node specified by handle nodeh. The new value is specified in the buffer valbuf, whose size is specified in nbytes.

For volatile properties, the write access function provided by the plug-in publishing the property is invoked.
