Function ABinderRpc_Accessor_delegateAccessor

pub unsafe extern "C" fn ABinderRpc_Accessor_delegateAccessor(
    instance: *const c_char,
    binder: *mut AIBinder,
    outDelegator: *mut *mut AIBinder,
) -> binder_status_t

Wrap an ABinderRpc_Accessor proxy binder with a delegator binder.

The IAccessorDelegator binder delegates all calls to the proxy binder.

This is required only in very specific situations when the process that has permissions to connect the to RPC service’s socket and create the FD for it is in a separate process from this process that wants to serve the Accessor binder and the communication between these two processes is binder RPC. This is needed because the binder passed over the binder RPC connection can not be used as a kernel binder, and needs to be wrapped by a kernel binder that can then be registered with service manager.

\param instance name of the service associated with the Accessor \param binder the AIBinder* from the ABinderRpc_Accessor from the ABinderRpc_Accessor_asBinder. The other process across the binder RPC connection will have called this and passed the AIBinder* across a binder interface to the process calling this function. \param outDelegator the AIBinder* for the kernel binder that wraps the ‘binder’ argument and delegates all calls to it. The caller now owns this object with one strong ref count and is responsible for removing that ref count with with AIBinder_decStrong when the caller wishes to drop the reference. \return STATUS_OK on success. STATUS_UNEXPECTED_NULL if instance or binder arguments are null. STATUS_BAD_TYPE if the binder is not an IAccessor. STATUS_NAME_NOT_FOUND if the binder is an IAccessor, but not associated with the provided instance name.
