Functions

func Madvise

func Madvise(b []byte, readahead bool) error

Madvise uses the madvise system call to give advise about the use of memory when using a slice that is memory-mapped to a file. Set the readahead flag to false if page references are expected in random order.

func Mmap

func Mmap(fd *os.File, writable bool, size int64) ([]byte, error)

Mmap uses the mmap system call to memory-map a file. If writable is true, memory protection of the pages is set so that they may be written to as well.

func Msync

func Msync(b []byte) error

Msync would call sync on the mmapped data.

func Munmap

func Munmap(b []byte) error

Munmap unmaps a previously mapped slice.
