Inter-process communication-General Linux technology-Linux programming and kernel information. The following is a detailed description. Now I have modified the etc/init. d/rcS file to the following:
./Main. out &
Sleep 5
Source modules/load_env.sh
./7105_qt-qws
With this modification, I can now run two processes through nfs to display my qt interface on the screen. But I want to communicate between the main process and the qt process. I don't know how to do this?
Some people said that I should study d-bus, but I didn't find that stlinux has such support. I don't know if it does?
If I want to use fork to generate sub-processes as described in Advanced Programming in the unix environment, it seems that it cannot be successful? Is my main. out working in the background from the script?
