• func CreateMemFD(name string, flags int) (int, error)

Functions

func CreateMemFD

func CreateMemFD(name string, flags int) (int, error)

CreateMemFD creates a memfd file and returns the fd.

func MapFile

func MapFile(addr, size, prot, flags, fd, offset uintptr) (uintptr, error)

MapFile returns a memory mapping configured by the given options as per mmap(2).

func MapSlice

func MapSlice(addr, size, prot, flags, fd, offset uintptr) ([]byte, error)

MapSlice is like MapFile, but returns a slice instead of a uintptr.

func UnmapSlice

func UnmapSlice(slice []byte) error

UnmapSlice unmaps a mapping returned by MapSlice.
