consumer/producer in c++

Question

This is a classic c/p problem where some threads produce data while other read the data. Both the producer and consumers are sharing a const sized buffer. If the buffer is e

Answer 1

What I would do is this:

• Make a data class that hides your queue
• Create thread-safe accessor methods for saving a piece of data to the q, and removing a piece of data from the q ( I would use a single mutex, or a critical section for accessors)
• Handle the case where a consumor doesn't have any data to work with (sleep)
• Handle the case where the q is becoming too full, and the producers need to slow down
• Let the threads go willy-nilly adding and removing as they produce / consume

Also, remember to add a sleep into each and every thread, or else you'll peg the CPU and not give the thread scheduler a good spot to switch contexts and share the CPU with other threads / processes. You don't need to, but it's a good practice.
