git_diff_patch_line_stats

Version:

Get line counts of each type in a patch.

This helps imitate a diff --numstat type of output. For that purpose, you only need the total_additions and total_deletions values, but we include the total_context line count in case you want the total number of lines of diff output that will be generated.

All outputs are optional. Pass NULL if you don't need a particular count.
