Struct shared_memory::SharedMemRaw

pub struct SharedMemRaw { /* private fields */ }

Raw shared memory mapping

This feature is only useful when dealing with memory mappings not managed by this crate. When all processes involed use the shared_memory crate, it is highly recommended to avoid SharedMemRaw and use the much safer/full-featured SharedMem.

Implementations

impl SharedMemRaw

pub fn create(
    unique_id: &str,
    size: usize
) -> Result<SharedMemRaw, Box<dyn Error>>

Creates a raw mapping

pub fn open(unique_id: &str) -> Result<SharedMemRaw, Box<dyn Error>>

Opens a raw mapping

pub fn get_size(&self) -> &usize

Returns the size of the raw mapping

pub fn get_path(&self) -> &str

Returns the OS specific path of the raw mapping

pub fn get_ptr(&self) -> *mut c_void

Returns a void pointer to the first address of the mapping
