> The API returns a list of fi_info structures on success or an error. This could be changed to:
> - Return fi_info structures even if an error is returned
> - Return multiple error codes + fi_info list
> - Carry error information as part of fi_info
This last option seems nice.
How much work is it to modify the fi_info structure?
> It's a matter of complexity being exposed to the user.
> We've also discussed adding runtime options to disable built-in providers as a work-around for buggy providers.
This is also a nice option - but again I don't have a feel for the amount of work this involves.
