I need to write an objective-C foundation tool which does not
terminated except when instructed to. Additionally it needs to
continue to respond to additional input as it is called from another
application and monitor for changes on the USB bus.
What I want it to do is:
When First launched:
-> create a list of objective-C objects based on attached custom USB
hardware
-> perform a function based on the command line argument
-> return result
-> wait for next call & idle
When idling:
-> monitor the USB bus in order to add / delete objects from our list
based on insertion / deletion of our custom USB hardware
-> terminate if none of our custom USB hardware exists
-> otherwise wait for next call & idle
On Subsequent call
-> perform a function based on the command line argument
-> return result
-> wait for next call & idle
Currently I have all this running in a Cocoa app, however they now
want to be able to call it from the UNIX command line.
Can anyone direct me to an example program which maintains a run loop
(extra points if it monitors for USB insertions / deletions)?
