Client development, get available devices - by: JuTs

Hi,

I want to integrate INDI in an existing software. I would like to know how I can get the available devices for a given type (e.g. : telescope, camera).

So far I managed to retrieve all the devices information with the command <getProperties version="1.7"/>. But how can get the list, for example, of all available cameras ? I haven't seen any information in the data returned by getProperties that let me know the type of device.

Regards

Julien
