Introduction

The proposed problem is a classical producer-consumer scheme in which there is just 1 producer and one consumer manipulating the bytes in a shared circular buffer. In particular, the shared buffer will be a an array of chars in which the producer writes one byte at a time getting it from a default string. We are going to use sem_wait and sem_post as primitives to provide semaphore functionality.

Tasks

What has to be done is:

• Complete the initialization of the variables
• Implement the Producer
• Implement the Consumer

That's all.

Compile and Run

To compile these programs, run:

make clean
make

To run your own implementation (ds7.c):

./prodcons

Extensions

We will also discuss two extensions of this work:

• A periodical print of the status of the shared buffer
• A n-prodicers, m-consumers version of the same problem
