Overview
Package syscall contains an interface to the low-level operating system
primitives. The details vary depending on the underlying system, and by default,
godoc will display the syscall documentation for the current system. If you want
godoc to display syscall documentation for another system, set $GOOS and $GOARCH
to the desired system. For example, if you want to view documentation for
freebsd/arm on linux/amd64, set $GOOS to freebsd and $GOARCH to arm. The primary
use of syscall is inside other packages that provide a more portable interface
to the system, such as “os”, “time” and “net”. Use those packages rather than
this one if you can. For details of the functions and data types in this package
consult the manuals for the appropriate operating system. These calls return err
== nil to indicate success; otherwise err is an operating system error
describing the failure. On most systems, that error has type syscall.Errno.
NOTE: This package is locked down. Code outside the standard Go repository
should be migrated to use the corresponding package in the golang.org/x/sys
repository. That is also where updates required by new systems or versions
should be applied. Signal, Errno and SysProcAttr are not yet available in
golang.org/x/sys and must still be referenced from the syscall package. See
for more information.
