I want to write a program where I can specify the maximum amount of RAM it can use after startup. I therefore need a function that shows me the current value of RAM that the running program is currently using.

Can someone help me with this?

The functions under `https://docs.julialang.org/en/v1/base/base/#System`  
do not seem to be suitable for this.

This thread might help. I was going to suggest looking at /proc//statm but that is Linux specific

Thanks for pointing that out, because it’s a start. Julia should get something built in to solve this elegantly for all operating systems uniformly
