The NIF first executes part of the + long-running task, then calls <c>enif_schedule_nif()</c> + to schedule a NIF for later execution to continue the + task. Any number of NIFs can be scheduled in this manner, + one after another. Since the emulator regains control + between invocations, this helps avoid problems caused by + native code tying up scheduler threads for too long.</p> + <p> + The <c>enif_schedule_nif()</c> function also replaces the + <c>enif_schedule_dirty_nif()</c> in the experimental + dirty NIF API.
