sequence_number/sample_pool question?

How does an sflow collector know when the agent has "reset the sample_pool"?

I am writing my own collector and I want to know if any datagrams have bee lost.
 Is the correct procedure to check the "current" sample_pool value against the
"last" sample_pool value and if the current is smaller they "reset" the
sequence_number?

Does this sound right?

Thanks for your help

unsigned int sequence_number;
/* Incremented with each flow sample
    generated by this source_id.
    Note: If the agent resets the
    sample_pool then it must
   also reset the sequence_number.*/
