Supported APIs

There are two use-cases that I am have thought of:

• ...code...
  int a, b, c;
  Checkpoint<> check;
  store(check, a, b, c);
  ...code...
  

• ...code...
  int a, b, c;
  Checkpoint<> check1;
  Checkpoint<> check2;
  Checkpoint<> check3;
  store(check1, a);
  ...code...
  store(check2, b);
  ...code...
  store(check3, c);
  ...code...
  

I do not currently support calling store multiple times on a checkpoint. Enabling this functionality would result in multi-threading issues.

A complete implementation could look like this:

• ...code...
  int a, b, c;
  checkpoint archive("previous_data.txt");
  revive_checkpoint(archive, a, b, c);
  ...code...
  hpxio_file backup_file("backedup_data.txt");
  checkpoint backup = save_checkpoint(a, b, c);
  backup_file.write(backup);
  

Futurized it would look like this:

• ...code...
  int a, b, c;
  checkpoint archive("previous_data.txt");
  revive_checkpoint(archive, a, b, c);
  ...code...
  hpxio_file backup_file("backedup_data.txt");
  hpx::future<checkpoint> backup = save_checkpoint(a, b, c);
  backup_file.write(backup.get());
