This previous post describes how TCT Tool was written, It is using POSIX Message Queue to exchange data. Basic on work, TCT Tool's message queue implementation almost work, only the main problem is the sender could read it's sent data, this sound weird because the TCT Tool would read it's data that intended to be read by the TCT. On the Toll, this problem hung up the TCT.
I change the IPC implementation using UNIX Domain Socket, first with datagram socket, the problem was just like the message queue, the TCT Tool receive it's sent data. The TCT Tool was not work until I use reliable stream socket, here the source code.
