Functions ¶

func Create ¶

func Create() (*os.File, error)

Create returns a file that can be mmapped to share memory with another process. It is possible for it to return both a valid file and an error.

Types ¶

type Mmap ¶

type Mmap []byte

Mmap is a []byte that represents a mmapped file.

func MapPrivate ¶

func MapPrivate(file *os.File, size int, prot int) (Mmap, error)

MapPrivate maps file into memory at the given size with the given prot. It maps it in private mode, meaning that writes to the memory will not be reflected in the file.

func MapShared ¶

func MapShared(file *os.File, size int, prot int) (Mmap, error)

MapShared maps file into memory at the given size with the given prot. It maps it in shared mode, meaning that writes to the memory will be reflected in the file.

func (Mmap) Unmap ¶

func (mmap Mmap) Unmap() error

Unmap unmaps mmap.
