C Program For Producer Consumer Problem

Let us learn how to solve producer consumer problem in C programming language. This C program to solve producer and consumer problem makes use of PThreads and Mutex. However, you can solve this problem by

However, you can solve this problem by Monitors and Semaphores as well. However, the given method below is one of the easiest one. pThreads stands for POSIX Threads.

 

What is Producer Consumer Problem?

The Producer-Consumer issue is a Classic Synchronisation Problem. It is also known as Bounded Buffer Problem. This problem focuses primarily on two different tasks: Producer and Consumer. Both of them share a fixed size and a common buffer.

  • The producer creates data and puts it into the buffer and restarts it.
  • The consumer consumes the data. In other words, the consumer removes the data from the buffer that the producer has created.

The producer and consumer problem are to ensure that the producer should not create data into the buffer memory once it gets full and simultaneously, the consumer should not remove data from a buffer memory that is empty. The

The Producer-Consumer problem can be resolved by placing a semaphore in the buffer.

    Finally, after a lot of errors and finding code from different websites, this program works. The pThreads in producer consumer problem seem to be comparatively easy than monitors and other methods.

      So what i think is if i put the pthread creation statements for producer and consumer inside a loop and create multiple pthread, will that do? Thanks

    Solvibg producer consumer problem using Mutex is mych more efficient and logical than other methods. It is easy to code as well.

    With Semaphores, producer consumer problem looks much better I feel.
