dear teachers:
The following program is the callback described in Berkeley Lab's Checkpoint Restart, but I confuse with the cr_checkpoint(0),why does its returning value have two kinds(0 and positive).According to my understanding,my_callback is called when user Send the application a signal that tells it to checkpoint or when checkpoint is completed.
thanks a lot
best wishes

my_callback {
/* cr_checkpoint() returns twice. */
ret = cr_checkpoint(0);
if (ret > 0) {
checkpoint_status = restart;
} else if (ret == 0) {
checkpoint_status = continue;
} else {
checkpoint_status = error;
}
return 0;
}
