Cloning repository

Prerequisites

Prerequisites for running thread pool unit tests

• with using Docker:

  • Docker

• without using Docker:

  • GCC with C++17 standard support
  • CMake >= 3.7
  • Git
  • pthread library

Prerequisites for using thread pool in project with CMake

Running unit tests

Running unit tests with using Docker

Being in root directory of project run in terminal:

sudo test/buildAndRunTestsDocker.sh

Running unit tests without using Docker

Being in root directory of project run in terminal:

Using thread pool library in project with CMake

1. Add thread pool project using ExternalProject_Add function in CMakeLists.txt file.

2. Link libThreadPool.a static library to project target in CMakeLists.txt file.

3. Include DefaultFixedThreadPool.hpp header file from inc directory in header/source file:

   #include "DefaultFixedThreadPool.hpp"

4. Create thread pool instance:

   auto pThreadPool = thread_pool::DefaultFixedThreadPool::create();

5. Enqueue task in thread pool:

   auto exampleTask = [](int x)
     {std::this_thread::sleep_for(std::chrono::seconds(2));
     std::cout << "Hello from worker thread" << std::endl;
     std::cout << "Passed argument value = " << x << std::endl;};
   auto future = pThreadPool->enqueue(exampleTask, 10);

   Notice 1: In this example also chrono and iostream headers must be included.

   Notice 2: You can enqueue tasks and its arguments as rvalue objects. Then there will be invoked move constructors if exists for these class of objects.

6. Get result:

   future.get();
