How to get data from another process in Contiki-NG?

Question

I try to send data from A process to B process with contiki-NG and firefly.

This is sender part of A process

 PROCESS_THREAD(A_process, ev, data)
{ 
  ...
    int data=1;
    if(process_post(&led_example, PROCESS_EVENT_CONTINUE, &data_led)!=PROCESS_ERR_OK){
       printf("event could not be posted\n");
    }
...
}

This is receiver part of B process

 PROCESS_THREAD(B_process, ev, data)
{ 
 ...
   if(ev==PROCESS_EVENT_CONTINUE ){
     printf("data=%d",*(int*)data);
   }
 ...
}

I checked event is delivered well. But problem is the data. I expected that B process print "data=1" but print garbage value ("data=2118363"). (I know process_data_t is void*(void pointer))

How can I get right value? Thank you.

Try declaring like :

static int data_led;
