git_diff_patch_from_blobs

Version:

Directly generate a patch from the difference between two blobs.

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