Hi,
I think that better to solve this task with shared memory... You can
look at the example in QtCreator sources (qtsingleapplication.cpp)

(initial value = 1) and lock it, but there is a single method aquire()
which blocks forever if the value is 0. So I can just make the second
process freeze forever until the first one exits.

Hello,
Have you tried a system semaphore? It should work in this case as
far as I know.
