I call a library routine
It returns without an error. The path is valid. I can open the file using
std::fopen. All is well. Now I want to store that path somewhere so I can
access it again when my application is restarted. I can't do that. The path
may be relative, and there is no guarantee that it will refer to the same
file next time I fopen() it.
I need to interoperate with a piece of code (library, executable) that is
affected by the current directory.
