Short circuit evaluation for trigger expressions?

[azabbixuser]

I am trying to find out if Zabbix does short circuit evaluation with trigger expressions, particularly for the logical & operator.

I've tried the search function for the forum.
The Zabbix 1.8 book doesn't state it either.
I've tried Google and the closest I can find is this link.
Is the author saying that now it does do short circuit evaluation?
I don't quite understand.

Thanks

I answered my own question: it does do short circuit evaluation.

I looked at the source code, particularly the function "evaluate_simple" in the file src/libs/zbxserver/expression.c.

A code snippet reveals this:

case '&':
	*result = (SUCCEED != cmp_double(value1, 0) && SUCCEED != cmp_double(value2, 0));
	break;

There is no compiler directive present that turns off short circuit evaluation. So, however C does it, is the way Zabbix does it. Case closed.
