No, it doesn't. Where did you get the idea that 'rwb' is a valid fopen
mode? It's not. If you need to read and write an existing file, you want
"r+b".

Perhaps your Linux C runtime library accepts the fopen mode 'rwb', but if
it does, it's a non-standard extension.

It works correctly if you use it correctly.
