dotnet cross-platform interop with C via Environment.ProcessId system call
The goal of this article is to understand how high-level dotnet code interoperates with low-level C code in a cross-platform manner
when making system call via Environment.ProcessId in dotnet.
We'll delve into the differences between running it on windows and unix-like (macOS, Linux) operating systems in a cross-platform manner.
We'll also write some C code to check and prove that we really understand what's going on.
