Re: [SR-Users] How to check a bit (1/0) of a pseudo-variable?

Hello,

that function is probably for ser-like AVPs.

back to your original need, you can use directly if conditions like:

if($var(x) & 2) { ... }

will be true if the second bit is set. You have to use the power of two for the appropriate integer value to match the bit position. The master branch has bitwise left/right shift operations as well -- I was thinking of backporting since they were in 1.x but lost in integration of the core interpreter for 3.0, reported by Juha, so it is not really a new feature:

I've found isavpflagset() right now:

http://sip-router.org/wiki/cookbooks/core-cookbook/devel#isavpflagset

But it has no description. How is it supposed to work?

The Changelog file says:

---

       Every AVP may by flaged from script via setavpflag(avpid, flag)
       (it's similar like message flags setflags,resetflags,isflagset).
       AVP flags must be declared using avpflags statement. Flags may be
       tested via isavpflagset(avpid, flag). Both the setting and
       testing may also be processed in a module. It's currently used in
       the "rr" module for dialog_cookies. Such module should register
       flag using register_avpflag(flag_id).

       Example: avpflags myflag, dialog_cookie;

       $a = 123; setavpflag($a, "myflag");

       if (isavpflagset($a, "myflag")) { ....

       $dlg_foo = "foo"; $dlg_bar = "bar"; setavpflag("$f./^dlg_",
       "dialog_cookie");

But is says that I must use setavpflag() to set flags in the AVP. In my case, I retrieve the AVP value from a database (an integer field). Could it work?
