Functions

func MAdvise

func MAdvise(b []byte, randomRead bool) error

MAdvise provide advice on memory usage. If the page references are expected to be in random order, set the randomRead flag to true.

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 syncs the mapped data

func MUnmap

func MUnmap(b []byte) error

MUnMap unmaps a mapped slice
