In this chapter, let's use the SP framework to create a simple message Program (why is this the most simple one? It can also reflect the speedphp function. I personally think that simplicity is beautiful, can also be understood more quickly ~),It is very effective to use instances to learn program development. At the same time, we can also understand the development process of the actual network project.This example will be provided for you to download later ~ First, let's take a look at the req

entries that do not copy the parent process.The implementation of the Vfork () system call is done by passing a special flag to the clone () system call.3.4 Implementation of threads in Linux3.4.1 Creating ThreadsCreating a thread is similar to creating a normal process, except that you need to pass some parameter flags when invoking clone () to indicate which resources need to be shared:Clone (CLONE_VM | Clone_fs | Clone_files | clone_sighand,0);The parameter flags passed to clone () determine

like user spaceThe memory in the kernel is not paged. Difficult to perform floating-point arithmetic during kernel programming The kernel gives each process only a small fixed-length stack Because the kernel supports asynchronous interrupts, preemption, and SMP, you must always be aware of synchronization and concurrencySMP: Symmetric multi-processing system. Common ways to solve competition: spin locks and semaphores. To consider the importance of portabilitysuch as keeping the

List-based information structure is commonly used in Web pages. It is similar to form-based top-down information distribution. For example, information flows commonly used in Facebook and other social media websites, and product lists commonly used in many e-commerce websites are in List-based information structures. There are many studies on the List structure. Its advantage is that it complies with the two basic rules of natural reading-from top to bottom, from left to right. However, after t
