git_diff_tree_to_tree

Version:

Create a diff with the difference between two tree objects.

This is equivalent to git diff <old -tree> <new -tree>

The first tree will be used for the "old_file" side of the delta and the second tree will be used for the "new_file" side of the delta. You can pass NULL to indicate an empty tree, although it is an error to pass NULL for both the old_tree and new_tree.
