llvm - Is there a way to access environment variables in an LLVM pass

Question

I was wondering if there was a way to access environment variables while writing an LLVM pass. In my source file, I read a certain environment variable, depending on whose value the execution is furthered. I ought to recreate that in my pass and add a few checks therein.

I would really appreciate if there was some tutorial laying out these details in form of examples.
