If you need such a boolean, it would be better to make is coupling_implicit. Usually we assume that implicit coupling is the special case that requires special treatment. You could then still write if (!coupling_implicit).

But I think you don't need this check in the first place, it should be enough to call what you want always.

sure, !coupling_implicit or coupling_explicit is no problem. But a check is needed. Because the call I want to happen always is only in the case of explicit coupling. For implicit coupling it should follow Precice_IsWriteCheckpointRequired() (only at the ends of coupling iterations).

This would then almost always be true, right? I understnad that you always want checkpoints to be stored (to trigger some internal update).

For explicit coupling, yes.
