[PATCH 3/4] libhal support for addon singletons
Rob Taylor
rob.taylor at codethink.co.uk
Fri Jun 1 04:39:53 PDT 2007
Adds api to libhal for supporting addon singletons:
- libhal_device_singleton_addon_is_ready for singletons to signal readyness.
- libhal_ctx_set_singleton_device_added and
libhal_ctx_set_singleton_device_removed for setting a callback on singleton
DeviceAdded/Removed. The properties of the new device are passed as a
LibHalPropertySet to the callback.
- a number of direct accessors for properties in a LibHalPropertySet
