[Rock-dev] Asynchronous method to write on InputPorts

[Javier Hidalgo Carrió]

Hi,

I am trying to write information in an Input port using the
Orocos::Async interface in ruby.
My question is how to access to an Input port in an asynchronous manner,
in a similar way when using the "blocking/non-async" method.

I am trying the following

locomotion_control = Orocos::Async.proxy 'locomotion_control'
locomotion_control.on_reachable do
motion_cmd = Types::Base::Commands::Motion2D.new
motion_cmd.translation = translation
motion_cmd.rotation = rotation
port = locomotion_control.port('motion_command')
port.write(motion_cmd)
end

But the write method is expecting another type. Does anyone know how to
do it?
the write method expect something like:

def write(sample,&block)
if block
[...]
end


Thanks,

Javier.

end

port.write(sample) do |result,error|
puts "could not send sample" if error
end

port.write(sample) do |result|
# will only be called if sample was sent
end
