Struct Pipe 

pub struct Pipe { /* private fields */ }

Implementations

impl Pipe

pub fn new(default_pipe_capacity: usize) -> PipeHandle

pub fn open( locked: &mut Locked<Unlocked>, current_task: &CurrentTask, pipe: &Arc<Mutex<Self>>, flags: OpenFlags, ) -> Result<Box<dyn FileOps>, Errno>

pub fn add_reader(&mut self)

Increments the reader count for this pipe by 1.

pub fn add_writer(&mut self)

Increments the writer count for this pipe by 1.

pub fn on_close(&mut self)

Called whenever a fd to the pipe is closed. Reset the pipe state if there is not more reader or writer.

pub fn read(&mut self, data: &mut dyn OutputBuffer) -> Result<usize, Errno>

pub fn write( &mut self, locked: &mut Locked<FileOpsCore>, current_task: &CurrentTask, data: &mut dyn InputBuffer, ) -> Result<usize, Errno>

pub fn splice( from: &mut Pipe, to: &mut Pipe, len: usize, ) -> Result<usize, Errno>

Splice from the from pipe to the to pipe.

pub fn tee(from: &mut Pipe, to: &mut Pipe, len: usize) -> Result<usize, Errno>

Tee from the from pipe to the to pipe.
