Function AIBinder_forceDowngradeToSystemStability

pub unsafe extern "C" fn AIBinder_forceDowngradeToSystemStability(
    binder: *mut AIBinder,
)

Given a binder interface at a certain stability, there may be some requirements associated with that higher stability level. For instance, a VINTF stability binder is required to be in the VINTF manifest. This API can be called to use that same interface within the system partition.

WARNING: you must hold on to a binder instance after this is set, while you are using it. If you get a binder (e.g. ...->asBinder().get()), you must save this binder and then use it. For instance:

auto binder = ...->asBinder();
AIBinder_forceDowngradeToSystemStability(binder.get());
doSomething(binder);
