Functions

func Munmap

func Munmap(d *Data) error

Munmap unmaps the given file from memory.

Types

type Data

type Data struct {
	Data []byte
	// Some windows magic
	Windows interface{}
	// contains filtered or unexported fields
}

The backing file is never closed, so Data remains valid for the lifetime of the process.

func Mmap

func Mmap(f *os.File, data *Data) (Data, error)

Mmap maps the given file into memory. When remapping a file, pass the most recently returned Data.
