[Fuseki] How to know result size ?

[Camel Christophe]

Hi everybody,

I'm writing a small web interface and that displays results with
pagination. So I send a sparql query with the keyword "LIMIT" and
"OFFSET". To calculate the total number of pages, I need to know the
total number of results for a query. 

How can I do that ? It seems that the count (*) syntax does not work
with Fuseki.

Thanks.

Chris.
