in reply to IPC Message Queues with IPC_NOWAIT

IPC::MSG exposes rcv() which calls msgrcv internally, are you sure you are using IPC::MSG? =)

    Busted, this is my first IPC app. I did some testing and did remove the IPC::MSG and no I am not using that module. It's just the IPC::SysV. But I still cannot pass it the flag of IPC_NOWAIT to the msgrcv function. (Well I should say, I can pass it that, but it's not making a difference...) Thanks,

      Post some code, I want to see hw you are importing the IPC_NOWAIT flag and the rest of the setup of the objects. Also what OS are you doing this on?

        This is FreeBSD 5.1, perl 5.6.1. 
        use IPC::SysV qw(IPC_PRIVATE IPC_CREAT S_IRWXU);

$id = msgget(4335, IPC_CREAT | S_IRWXU);

$go = 1;

while($go){

        if(msgrcv($id, $rcvd, 512, 0, IPC_NOWAIT)){
                ($typ_rcvd, $rcvdData) = unpack("l! a*", $rcvd);
                print "Got------>$rcvdData\n";
        }
print "Wait\n";
sleep 1;
}
