An explanation of the defer statement in the official documentation: The defer statement delays execution of a function that is deferred until the program that contains it returns (the function that contains it executes the return statement/run to the end of the function automatically returns/corresponds to the goroutine panic) execution. Each time the defer statement executes, the return value and parameter values of the defer decorated function are

function calls-Common Language resource cleanup, file closing, unlocking, and recording time- Modify function calculation result after return by cooperating with anonymous function-If a variable in the function body is a parameter of an anonymous function when defer, then a copy is obtained when the defer is defined, or the address of a variable is referenced-Go has no exception mechanism, but has panic/recover mode to handle errors-

And the cause of the crash is confusing, it is difficult to fathom. In fact, the normal condition of the crash can be avoided. The following crash root hints, may let you avoid it, enjoy being a computer fan. 1. Installing too many operating systems on the same hard drive can cause the system to

One, computer crash performance The performance of the computer crash, including failure to start the system, the screen "freeze" no response, the mouse, keyboard can not be entered, the software operation abnormal interruption. Although the cause of the crash is manifold, but same, the reason can never be separated from the hardware and software two aspects. Second, the cause of the crash 1, installing too many operating systems on the same hard drive can cause the system to

The crash is something that makes the operator rather annoying. When the performance of the crash is "blue screen", unable to start the system, the screen "freeze" no response, the mouse, keyboard can not be entered, the software operation abnormal interruption.

Go language Development (vii), GO language error handling One, defer delay function 1. Introduction to defer delay function Defer is not executed immediately at the time of Declaration, but after the function return, followed by the Filo (advanced out) principle of each defer, typically used for exception handling, freeing up resources, cleaning up data, logging, and so on.Each time the defer statement executes, the return value and parameter values of the defer decorated function are evaluated
