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

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
