How to avoid using send()/sendDelayed() function in multiple places at the same time？

[Alexander Wang]

Hello:

     Is there a function that can detect if a module is currently using the send()/sendDelayed() function? I just want to avoid the following questions：

Thanks very much!

You can check if the packet is scheduled already

 

if (!pkt->isScheduled())

Hello, Alfonso:

      Thanks for your replay! I am also intend to use this way, but if I check by xxx->isScheduled() in other module, but I do not know the xxx'name in this module.

It is the packet

if (!pkt->isScheduled())  send(pkt,”out”);

 

But if you have this error is that you have something strange in the code, in the moment that a module sends a packer the module must ignore/delete the references to the packet, for example

send(pkt,”out”);

pkt = nullptr;

For efficiency, the simulators send the packet instead of a copy of the packet.

Alfonso, Thank you very much! I make a stupid mistake just like below:

for(xx;xx;xx){

    send(xx);

}
