Generally, use an Arc,
#Shared memory
surreal bay
It's kept on the heap, and the reference counting means the memory has a lifetime which will last, as long as a thread has a handle to the memory,
Or channels, if you want to use a unidirectional system for sending data...

What is a process in this context?
The above advice is not suitable then
You're looking for "inter process communication"
If you can avoid having multiple processes that would be better
surreal bay
Oof... I read it as "threads" instead...
Yeah, if you need shared memory, using threads would be more appropriate, if possible.

not always
what are you exactly trying to do?
launch executable a from rust program b?
you might not need ipc
This should've been the first question
Do you want any other communication or just detect if it's open or not? (e.g. as in game launchers where they have to detect whether it's open but no more than that)
IPC is not meant for this
I am thinking create a blank file from the child program and delete it when you close the program
Maybe you want to do this with a blank rust app first, then integrate that into your main program
Does that make sense?
reg?
why would you do that?
there's a few cons I can think of if you do that:
- need admin privilidges
- not cross platform
- not strictly needed in this case/simpler alternatives
you can do that
But I wouldn't recommend
okay
no prob

I didn't know. Thanks for sharing your knowledge!
