Re: [liblo] Deleting a given handler for a method

[Philippe M. <pm...@ac...>]

Hi Cam,

I thought including path and typespec might be useful when the same handler has been registered for multiple methods and one want to unregister it for only a given method. But I don't know if this is a need in real-life use cases. In my case, the simpler API you describe would be ok.

Thx

Phil
