QuestionThread synchronization problem Pin
samzcs10-Sep-18 9:12

Hi, I met a thread synchronization scenario in a small code.
//task A: 
if (rcvd == true)  
{
  read rcv_buffer
   ...
  rcvd = false;
}

//task B:
dataCB(int ch_id, char *buf, int len, char stat)
{
  rcvd = true;
  receivenotify(chid, rcv_buffer, sizeof(rcv_buffer), dataCB,0);
}


here, rcvd = false in task A, can't stop task B produce data. how can I let task A, B synchronized.
add if (rcvd == false) in task B before receivenotify()? is that a dead lock ?

Thanks
