IO::Mux::File::Read - write to file

 IO::Mux::File::Read
   is a IO::Mux::Handler::Read
   is a IO::Mux::Handler

  my $mux = IO::Mux::Select->new;  # or ::Poll

  use IO::Mux::Open '<';
  my $file = $mux->open('<', $filename);

  use IO::Mux::File::Read;
  my $file = IO::Mux::File::Read->new(file => $filename);
  $mux->add($file);

  $file->getline(sub {print "\n"});

In an event driven program, reading is harder to use than writing: the read will very probably be stalled until data has arrived, so you will need a callback to handle the resulting data.

IO::Mux::File::Read->new(OPTIONS)

 -Option   --Defined in     --Default
  exclusive                   <false>
  fh         IO::Mux::Handler  <required>
  file                        <required>
  mode                        '<'
  modeflags                   <undef>
  name       IO::Mux::Handler  '<$file'
  read_size  IO::Mux::Handler::Read  32768

exclusive => BOOLEAN

fh => FILEHANDLE

file => FILENAME|HANDLE

mode => '<'

For now, the mode is always simply

modeflags => INTEGER

When defined, the exclusive option is not used, but your value is taken. Use constants defined by Fcntl. Do not forget to include O_NONBLOCK.

name => STRING

read_size => INTEGER
