dtrace discuss - Oct 2007 - Can we use aggregation in predicate?

Hi,
My script is as follows...
pid$target:::entry
{
  @Count[probefunc] = count();
}
pid$target:::return
/Count[probefunc] != 1/
{
  ---------------
  ---------------
}
But it gives error.
: in predicate: Count has not yet been declared or assigned

Is it valid?

Thanks,
Ajit

No it''s not. You can''t use an aggregation in a predicate. I
suggest you take
a look at the chapter in the Solaris Dynamic Tracing Guide on aggregations.
