Go provides various runtime and system programming APIs that allow developers to access and control the underlying system resources and environment in Go programs. Some of the key areas where these APIs are commonly used include low-level system programming, operating system interface, hardware interaction, system-level administration, and more.
Here are some examples of Go's runtime and system programming APIs and their uses:
Operating System Interface (OS): Go's OS package provides a set of functions that allow developers to interact with the underlying operating system. For instance, you can use this package to retrieve the system's hostname, environment variables, command line arguments, process ID, and more.
File System: Go's os and ioutil packages provide functions for reading and writing files, manipulating directories, and managing file permissions. This makes it easy to work with files and directories in Go programs.
Network Programming: Go's net package provides a set of functions for creating and manipulating network connections, listening for incoming connections, and working with network protocols such as TCP, UDP, and HTTP. This makes it easy to build networked applications and services in Go.
System Administration: Go's os/exec package provides a way to execute external commands and scripts from Go programs. This can be useful for performing system-level administration tasks such as running backups, installing software, and more.
Low-Level System Programming: Go's unsafe package provides a way to bypass the Go type system and access memory directly. This can be useful for low-level system programming tasks such as working with pointers and manipulating memory.
These are just a few examples of the runtime and system programming APIs available in Go. By providing access to low-level system resources and interfaces, Go makes it possible to build highly performant and efficient system-level software in Go.
