git_diff_foreach

Version:

Loop over all deltas in a diff issuing callbacks.

This will iterate through all of the files described in a diff. You should provide a file callback to learn about each file.

The "hunk" and "line" callbacks are optional, and the text diff of the files will only be calculated if they are not NULL. Of course, these callbacks will not be invoked for binary files on the diff or for files whose only changed is a file mode change.

Returning a non-zero value from any of the callbacks will terminate the iteration and return the value to the user.
