C computer deadlock in program sample

In this article, I am going to discuss Deadlock in C with example. Please read our previous article where we discussed Semaphore in C with some examples.

Deadlock is one of the most important aspects to understand as a developer. As part of this article, we are going to discuss the following pointers.

In simple words, we can define a deadlock in C is a situation where two or more threads are unmoving or frozen in their execution because they are waiting for each other to finish. The Thread1 locked the Resource1 and trying to acquire a lock on Respurce2. At the same time, Thread2 acquired a lock on Resource2 and trying to acquire a lock on Resource1. As you can see in the above image, Thread1 is waiting to acquire a lock on Resource2 which is held by Thread2.

Let us understand Deadlock in C with an example. Create a class file with the name Account. The above Account class is very straight forward. We created the class with properties i. ID and Balance. Through the constructor of this class, we are initializing these properties. So, at the time of Account class instance creation, we need to pass the ID and Balance value.

Here we have also created two methods. Related Articles. CPU Scheduling. Process Synchronization. Memory Management. Disk Management. Disk Scheduling. Operating System Quizes. Table of Contents.

Following program shows deadlock scenario, but the problem is why both "p1 trying to get rs2" and "p2 tying to get rs1" are not printing by proc1 and proc2 respectively It might have something to do with how you print the messages.

Try adding a newline last in the strings you print, or to explicitly flush the buffers with fflush. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
