C++ (Cpp) RNG_BACKEND Examples

Example #1

File: rng.c Project: JMR-b/qemu

static void rng_backend_prop_set_opened(Object *obj, bool value, Error **errp)
{
    RngBackend *s = RNG_BACKEND(obj);
    RngBackendClass *k = RNG_BACKEND_GET_CLASS(s);
    Error *local_err = NULL;

    if (value == s->opened) {
        return;
    }

    if (!value && s->opened) {
        error_setg(errp, QERR_PERMISSION_DENIED);
        return;
    }

    if (k->opened) {
        k->opened(s, &local_err);
        if (local_err) {
            error_propagate(errp, local_err);
            return;
        }
    }

    s->opened = true;
}
