write_all

fn write_all(Stream s, Vec<byte> buf) -> Result<int, IoError>

use io::sync::{write_all};

Writes all of buf to s, waiting whenever the stream is not ready.

io::write may write only part of a buffer; this keeps going until every byte is out, then returns Ok(0). Inside a task, the waits let other tasks run.

Parameters#

Returns#

Result<int, IoError>

Examples#

use io::sync::{write_all};
use tests::assert;
use io::{stdout};
use string::{to_bytes};
let written = write_all(stdout(), to_bytes("hi\n"));
assert!(written.is_ok());
