<div style="">One question regarding $sht. Does it need locking
like $shv does?</div>

depends what operation you do. A read does not need locking, a write
does not need, but updates that uses itself need.<br>

$shv(...) is referred as shared memory variable because it
stores the value in shared memory. That means if you set
$shv(x) in one process, you can read its value from
another process. You have to be sure you don't have races
in setting the variable, that could be achieved with locks
from cfgutils.<br>
<br>
$var(...) is referred as private memory variable because
it stores the value in private memory. That means its
value is valid in the context of the same process (e.g.,
use it while processing the same sip message on a single
routing block type, like running the main request route
block, or reply route block, etc). It is not safe to use
it for transactions, like setting it in request route
block and reading it in failure route block (use avps for
that case).<br>
<br>
$var(...) is faster to use and does not need locking at
all. These are usually referred as script variable, but
this term can be confused with all the config file
variables.<br>
<br>
Cheers,<br>
Daniel
