How to know how many result in total from a getRecords()

Hi,

I'm using getRecords() to get a list of accounts. However you need to set a page and a number of record (per page I guess). So the default is 200 results per page. But how do I know if there aren't more results than the limit ? For example, I have 700 Accounts, I already know today there is 300 records marching my request, but as the limit is 200, how do I know there are 100 records left out...

How do I know the total of results  ? What is the best way to handle this ?

Thanks
