Functions ¶

func Fd ¶

func Fd(f *os.File) int

Fd returns the integer file descriptor referencing the open file. The file descriptor is valid only until f.Close is called or f is garbage collected.

func Fsize ¶

func Fsize(f *os.File) int

Fsize returns the file size.

func Mmap ¶

func Mmap(fd int, offset int64, length int, prot int, flags int) (data []byte, err error)

Mmap calls the mmap system call.

func Msync ¶

func Msync(b []byte) (err error)

Msync calls the msync system call.

func Munmap ¶

func Munmap(b []byte) (err error)

Munmap calls the munmap system call.

func Offset ¶

func Offset(offset int64) int64

Offset returns the valid offset.

func Open ¶

func Open(fd int, offset int64, length int, p Prot) (data []byte, err error)

Open opens a mmap

func ProtFlags ¶

func ProtFlags(p Prot) (prot int, flags int)

ProtFlags returns prot and flags by Prot p.

Types ¶

type Prot ¶

type Prot int

Prot is the protection flag.

const (
	// READ represents the read prot
	READ Prot = 1 << iota
	// WRITE represents the write prot
	WRITE
	// COPY represents the copy prot
	COPY
	// EXEC represents the exec prot
	EXEC
)
