What is Boost ASIO?
Boost. Asio is a cross-platform C++ library for network and low-level I/O programming that provides developers with a consistent asynchronous model using a modern C++ approach. Asio to develop simple client and server programs. Examples. Examples that illustrate the use of Boost.
What is boost :: shared_ptr?
shared_ptr is now part of the C++11 Standard, as std::shared_ptr . Starting with Boost release 1.53, shared_ptr can be used to hold a pointer to a dynamically allocated array. This is accomplished by using an array type ( T[] or T[N] ) as the template parameter.
How does a Threadpool work?
A thread pool is a pool threads that can be “reused” to execute tasks, so that each thread may execute more than one task. A thread pool is an alternative to creating a new thread for each task you need to execute.
What do you understand by thread pool?
In computer programming, a thread pool is a software design pattern for achieving concurrency of execution in a computer program. Often also called a replicated workers or worker-crew model, a thread pool maintains multiple threads waiting for tasks to be allocated for concurrent execution by the supervising program.
How does Boost ASIO work?
At its core, Boost Asio provides a task execution framework that you can use to perform operations of any kind. You create your tasks as function objects and post them to a task queue maintained by Boost Asio. You enlist one or more threads to pick these tasks (function objects) and invoke them.
How do you build a Boost lib?
5.2. 1 Install Boost. Build
- Go to the directory tools/build/.
- Run bootstrap.sh.
- Run b2 install –prefix=PREFIX where PREFIX is the directory where you want Boost. Build to be installed.
- Add PREFIX/bin to your PATH environment variable.
How to create a thread pool using boost in C + +?
Any tasks * you add behind this point will not execute. */ ioService.stop (); /* * Will wait till all the threads in the thread pool are finished with * their assigned tasks and ‘join’ them. Just assume the threads inside * the threadpool will be destroyed by this method. */ threadpool.join_all ();
How to increase the number of threads in a pool?
Obtains the executor associated with the pool. Joins the threads. Notify the execution_context of a fork-related event. Stops the threads. Constructs a pool with an automatically determined number of threads. Constructs a pool with a specified number of threads. Destructor. Destroys all services in the context.
Can a host limit the size of the thread pool?
If the common language runtime is hosted, for example by Internet Information Services (IIS) or SQL Server, the host can limit or prevent changes to the thread pool size. Use caution when changing the maximum number of threads in the thread pool. While your code might benefit, the changes might have an adverse effect on code libraries you use.
How to submit functions to the thread pool?
The thread pool class is an execution context where functions are permitted to run on one of a fixed number of threads. To submit functions to the thread_pool , use the dispatch , post or defer free functions.
