Struct std::os::MemoryMap

pub struct MemoryMap {
    data: *mut u8,
    len: uint,
    kind: MemoryMapKind,
}

A memory mapped file or chunk of memory. This is a very system-specific interface to the OS's memory mapping facilities (mmap on POSIX, VirtualAlloc/CreateFileMapping on win32). It makes no attempt at abstracting platform differences, besides in error values returned. Consider yourself warned.

The memory map is released (unmapped) when the destructor is run, so don't let it leave scope by accident if you want it to stick around.

Fields

`data`	Pointer to the memory created or modified by this map.
`len`	Number of bytes this map applies to
`kind`	Type of mapping

Methods

`impl MemoryMap`

`fn new(min_len: uint, options: &[MapOption]) -> Result<MemoryMap, MapError>`

Create a new mapping with the given options, at least min_len bytes long. min_len must be greater than zero; see the note on ErrZeroLength.

`fn granularity() -> uint`

Granularity that the offset or address must be for MapOffset and MapAddr respectively.

Trait Implementations

`impl Drop for MemoryMap`

`fn drop(&mut self)`

Unmap the mapping. Fails the task if munmap fails.
