Which functions in golang use the standard library?

There are more than 150 built-in packages with common functions such as fmt, os, etc. in the Go language. They are called standard libraries, most of which (except some low-level ones) ) is built into Go itself. The full list can be viewed at Go Walker.                                                                                                                 (Recommended learning: go)

unsafe: Contains some commands that break the "type safety" of the Go language. They will not be used in general programs and can be used in C/C The program is being called.

syscall-os-os/exec:os: Provides us with a platform-independent operating system functional interface. It adopts a Unix-like design, hiding the differences between different operating systems, and allowing different file systems and operating systems to Objects behave consistently.

os/exec: Provides a way for us to run external operating system commands and programs. syscall: The underlying external package provides the basic interface for underlying calls of the operating system.

Restart Linux through a Go program to reflect its capabilities.

package main
import (
	"syscall"
)

const LINUX_REBOOT_MAGIC1 uintptr = 0xfee1dead
const LINUX_REBOOT_MAGIC2 uintptr = 672274793
const LINUX_REBOOT_CMD_RESTART uintptr = 0x1234567

func main() {
	syscall.Syscall(syscall.SYS_REBOOT,
		LINUX_REBOOT_MAGIC1,
		LINUX_REBOOT_MAGIC2,
		LINUX_REBOOT_CMD_RESTART)
}

archive/tar and /zip-compress: Compress (decompress) file function.

fmt-io-bufio-path/filepath-flag:

fmt: Provides formatted input and output functions.

io: Provides basic input and output functions, most of which are encapsulation around system functions.

bufio: Encapsulation of buffered input and output functions.

path/filepath: used to operate the target file name path in the current system.

flag: Operation of command line parameters.  

strings-strconv-unicode-regexp-bytes:

strings: Provides operations on strings.

strconv: Provides functions for converting strings to basic types.

unicode: Provides special functions for unicode strings.

regexp: Regular expression function.

bytes: Provides operations on character sharding.

index/suffixarray: Quick substring query.

math-math/cmath-math/big-math/rand-sort:

math: Basic mathematical functions.

math/cmath: Operations on complex numbers.

math/rand: Pseudo-random number generation.

sort: Sort arrays and customize collections.

math/big: Implementation and calculation of large numbers. 

container-/list-ring-heap: Implement operations on collections.

list: Double linked list.

ring: Ring linked list.
