[asterisk-users] Forking AGI or GoSub

[Dovid Bender]

Eric,

As I mentioned before that does not seem to work with PHP

  == Using SIP RTP CoS mark 5
    -- Executing [my_test_test at from-external:1]
NoOp("SIP/fpp-55559999-000009ca", "") in new stack
    -- Executing [my_test_test at from-external:2]
AGI("SIP/fpp-55559999-000009ca",
"fast_agi_wrapper,my_test,cnum=10000009&cname=Dovid Bender") in new stack
    -- Launched AGI Script /opt/dovid/fastagi/fast_agi_wrapper
 fast_agi_wrapper,my_test,cnum=10000009&cname=Dovid Bender: We are the
parent. Let's die!
 fast_agi_wrapper,my_test,cnum=10000009&cname=Dovid Bender: We are child
here. Taking a nap !
 fast_agi_wrapper,my_test,cnum=10000009&cname=Dovid Bender: That nap was
goooood!
    -- <SIP/fpp-55559999-000009ca>AGI Script
/opt/dovid/fastagi/fast_agi_wrapper completed, returning 0
    -- Executing [my_test_test at from-external:3]
Playback("SIP/fpp-55559999-000009ca", "tt-monkeys") in new stack
    -- <SIP/fpp-55559999-000009ca> Playing 'tt-monkeys.slin' (language 'en')
    -- Remote UNIX connection
    -- Remote UNIX connection disconnected


My code:
<?PHP


$pid = pcntl_fork();
if ($pid != 0) {
     // we are the parent
     // do parent stuff
        $fastagi->verbose("We are the parent. Let's die!");
     exit;
}

// we are the child, detatch from terminal
$sid = posix_setsid();
if ($sid < 0) {
     die;
}
// do child stuff

        $fastagi->verbose("We are child here. Taking a nap !");
        sleep(5);
        $fastagi->verbose("That nap was goooood!");

?>
