In addition to the effect of readability, line spacing itself is also a strong expressive design language, in order to enhance the layout of decorative effect, you can consciously widen or narrow line spacing, reflecting the unique aesthetic charm. For example, widening line spacing can reflect relaxed, relaxing emotions, and should be used for entertaining,
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 ~

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.
