[LinuxCNC/linuxcnc PR#339] Renew new user module hal2UI

#1 – SebKuzminsky 于 2017-10-04

@jasenk2 can you explain the purpose of this comp? It reads a struct from a unix domain socket and sets HAL pins accordingly, and writes a struct of HAL pin values to the unix domain socket?

This adds a new, special-purpose IPC mechanism. Why not have the process on the other side of the socket access the HAL pins directly, via nets/signals?

Yes it is designed to provide IPC to 32 pins and 1 32bit unsigned integer
for system proposes and specialized GUI
