Functions

func Fallocate

func Fallocate(fd int, mode uint32, off int64, len int64) error

func Getrusage

func Getrusage(who int, rusage *Rusage) error

func Ioctl

func Ioctl(fd int, request, argp uintptr) error

func Lstat

func Lstat(path string, statbuf *Stat_t) error

func Mount

func Mount(source string, target string, fstype string, flags uintptr,
	data string) error

func SetAllGid

func SetAllGid(gid int) error

func SetAllUid

func SetAllUid(uid int) error

func SetMyPriority

func SetMyPriority(priority int) error

SetMyPriority sets the priority of the current process, for all OS threads. On platforms which do not support changing the process priority, an error is always returned.

func SetNetNamespace

func SetNetNamespace(fd int) error

SetNetNamespace is a safe wrapper for the Linux setns(fd, CLONE_NEWNET) system call. On Linux it will lock the current goroutine to an OS thread and set the network namespace to the specified file descriptor. On failure or on other platforms an error is returned.

func Stat

func Stat(path string, statbuf *Stat_t) error

func UnshareMountNamespace

func UnshareMountNamespace() error

UnshareMountNamespace is a safe wrapper for the Linux unshare(CLONE_NEWNS) system call. On Linux it will lock the current goroutine to an OS thread and unshare the mount namespace (the thread will have a private copy of the previous mount namespace). On failure or on other platforms an error is returned.

func UnshareNetNamespace

func UnshareNetNamespace() (fd int, tid int, err error)

UnshareNetNamespace is a safe wrapper for the Linux unshare(CLONE_NEWNET) system call. On Linux it will lock the current goroutine to an OS thread and unshare the network namespace (the thread will have a fresh network namespace). The file descriptor for the new network namespace and the Linux thread ID are returned. On failure or on other platforms an error is returned.
