The C++17 filesystem api provides two alternatives, the standard 
filesystem_error exception and an output-paramater for capturing 
os-specific error codes. I'm not quite sure why they provide 
both, but I guess performance and the ability to compile for  
runtimes with exceptions turned off could explain it.

It is rather clear though that C++ std lib relies heavily on 
exceptions.
