Aha, got it.  I'd say a

    extern debuginfod_client *dwfl_get_debuginfod_client (Dwfl *);

type function would probably be your bet.  That could also be built
upon later, to provide finer grained control (to override environment
variable settings e.g.).


The other approach of a custom Dwfl_Callbacks .find_debuginfo hook is
also available, wherein your own app can take charge of finding /
downloading debuginfo, with its own bespoke debuginfod_client object.
This would have the benefit of working with existing elfutils.
