7// Package windows contains an interface to the low-level operating system
8// primitives. OS details vary depending on the underlying system, and
9// by default, godoc will display the OS-specific documentation for the current
10// system. If you want godoc to display syscall documentation for another
11// system, set $GOOS and $GOARCH to the desired system. For example, if
12// you want to view documentation for freebsd/arm on linux/amd64, set $GOOS
13// to freebsd and $GOARCH to arm.
14//
15// The primary use of this package is inside other packages that provide a more
16// portable interface to the system, such as "os", "time" and "net". Use
17// those packages rather than this one if you can.
18//
19// For details of the functions and data types in this package consult
20// the manuals for the appropriate operating system.
21//
22// These calls return err == nil to indicate success; otherwise
23// err represents an operating system error describing the failure and
24// holds a value of type syscall.Errno.
