git_patch_from_buffers

Version:

Directly generate a patch from the difference between two buffers.

This is just like git_diff_buffers() except it generates a patch object for the difference instead of directly making callbacks. You can use the standard git_patch accessor functions to read the patch data, and you must call git_patch_free() on the patch when done.
