Bubble sort won't sort anything...

Just my opinion, BlockInput() seems like a sledgehammer to crack a walnut. On a multi-tasking operating system, the user may wish to interact with other applications during that time but won't be able to.

Indeed, but I've tried every other possible way of blocking,removing,ignoring input and nothing has worked.

I don't know why that would be surprising. sync() isn't guaranteed to do anything at all on input streams.
