[openrtm-users 00853] Re: Ports configuration

[Masayuki Shimizu]

Hello, 

I translated the document in OutPort.h to English. 
Find the attached file. 
(perhaps it may include mistakes or strange translation.)
I hope this will help you. 

Dr. Ando, core developer of OpenRTM-aist, said that, 
as of 1.0.0-RC1, users cannot select the port buffer. 
Only ring buffer is available now. 
This limitation will be eliminated, he says, by release
version. 
(I expect NullBuffer will be come back in release
version.)

In addition, not all port callbacks does work in RC1
version. 
As you pointed out, OnWrite callbacks of InPort 
do not work currently. 
The OnWrite callbacks will be available by release
version. 

So, I think, you might wait release version, if you can
wait.
