BIN_OUTPUT¶

6.57.1. BIN_OUTPUT.new¶

`new` makes an `output` which builds a `bin`.

The result `output` also provides `bin` method. It returns a `bin` val which joins bytes passed to `write` method.

flush

`flush` method does nothing. It just tail-calls $success, if the `output` is not closed.

If the `output` is closed, `write` and `flush` methods cause an IO error, like other `output` implementations based on system resources.

Example

:BIN_OUTPUT.require_from('kink/io/')
:BIN.require_from('kink/')
:CONTROL.require_from('kink/')

:make_bin <- {
  CONTROL.with_finally{(:finally)
    :Out = BIN_OUTPUT.new
    finally{ Out.close }
    Out.write(BIN.of(1 2 3))
    Out.write(BIN.of(4))
    Out.bin
  }
}
stdout.print_line(make_bin.repr) # => (bin 0x01 0x02 0x03 0x04)
