## What it is
golang/sys provides supplemental Go packages for low-level interaction with the operating system, including syscall wrappers, constants, and types across Linux, macOS, Windows, BSD, and other platforms. It is the official golang.org/x/sys library maintained by the Go team as a mirror of the upstream repository.

## Use cases
- make raw system calls from Go
- query OS version and hardware info in Go
- interact with Windows APIs from Go
- use Unix domain sockets and ioctl in Go
- get process and memory information on Linux
- portable low-level OS access across platforms

## When to choose
- you need syscall-level access beyond Go's standard os/syscall packages
- you want official, well-maintained Go bindings for OS primitives
- you need cross-platform low-level constants and types
- you're building system tools or daemons in Go

## When to avoid
- you only need high-level file or process operations covered by the standard library
- you're not programming in Go
- you need a stable API guarantee - x/sys APIs can evolve

## Facets
- artifact type: library
- maturity: stable
- function: developer-tools, file-system, networking
- domain: operating-systems, developer-tools, cross-platform
- platform: windows, bsd, go
- tags: system-calls, os-interaction, golang-org, low-level, unix, windows-api, linux, macos
