I do not understand why even a single application in my system is using Message Queues?
I have so many applications installed and have them running(Ubuntu OS). I used Message Queues in one of my C application to transfer text messages between different threads.
Since I saw this, I have a feeling that Message Queues may not be ideal for data transfer as no one is using them. Is it completely safe to use message queues? Is there any possibility of memory corruption if we do not implement them properly?
