C++ thread pool

A simple thread pool implementation in C++

Getting Started

To use the thread pool in your project, you simply include the header where it's needed and add the .cpp implentation file in your compilation. Make sure that the header file is visible from the .cpp file. The preferred way of doing this is using the -I option of gcc/g++.

You also have to add the pthread library during the linking step, since the thread pool uses POSIX threads.

Example

#include <iostream>
#include "thread_pool.h"

using namespace std;

// Extending the base thread_pool::task class to provide void run() implementation.
class my_task : public thread_pool::task {
    private:
        int i;

    public:
        my_task(int i) : i(i) {}
        
        void run() {
            cout << "Hello from thread, i = " << i << endl;
        }
};

int main() {
    // Creating a thread pool with 4 threads.
    thread_pool thread_pool(4);

    // Adding jobs in the thread pool.
    for (int i = 0; i < 50; i++)
        thread_pool.add_task(new my_task(i));

    // Thread pool destructor will wait here, until all jobs are completed.
}
