String base = "/var/data";
String relative = new File(base).toURI().relativize(new File(path).toURI()).getPath();

&*(reverse_iterator(i)) == &*(i - 1)
(from a Dr. Dobbs article):
So you need to apply an offset when getting the base(). Therefore the solution is:
m_CursorStack.erase( --(i.base()) );

What's is the difference between include and extend in use case diagram?

Zero-based month numbering [closed]
...e of zero is also popular with pointer arithmetics where you would use one base pointer pointing at some allocated memory, plus a second pointer which would be at an offset from this base pointer. Here, using the value zero makes a lot of sense to point the offset to the base of the memory block. (G...

Difference between private, public, and protected inheritance
... accessors that I'm aware of: public, protected and private.
Let:

Everything that is aware of Base is also aware that Base contains publicMember.
Only the c...
