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.
