Implementations

impl MmapInner

fn new( len: usize, prot: c_int, flags: c_int, file: RawFd, offset: u64 ) -> Result<MmapInner>

Creates a new MmapInner.

This is a thin wrapper around the mmap sytem call.

pub fn map( len: usize, file: RawFd, offset: u64, populate: bool ) -> Result<MmapInner>

pub fn map_exec( len: usize, file: RawFd, offset: u64, populate: bool ) -> Result<MmapInner>

pub fn map_mut( len: usize, file: RawFd, offset: u64, populate: bool ) -> Result<MmapInner>

pub fn map_copy( len: usize, file: RawFd, offset: u64, populate: bool ) -> Result<MmapInner>

pub fn map_copy_read_only( len: usize, file: RawFd, offset: u64, populate: bool ) -> Result<MmapInner>

pub fn map_anon(len: usize, stack: bool, populate: bool) -> Result<MmapInner>

Open an anonymous memory map.
