Yad forking and return results

I'm trying to make a yad process collaborate with another (a mounter but that's not very important). I have a code structure like this (simplified) in the critical part: ` yad --list --button=gtk-close:1 --button=gtk-ok:0 "${CONF_LIST[@]}" 2>/dev/null & yad_pid=$! #3 is the file descriptor of the named pipe of the other process { read -u 3 line && kill -USR2 $yad_pid 2>/dev/null; } & pidof_killer=$! wait $yad_pid result=$? kill $pidof_killer 2>/dev/null #do something with result. My problem here is that part of what i need (besides the result) is the list selection. Previously to being a fork, i could just do VAR=$(yad ...) and get it in addition to the yad exit code, but now i don't know how to communicate it to the main process after the wait.
