git_diff_blob_to_buffer

Version:

Directly run a diff between a blob and a buffer.

As with git_diff_blobs, comparing a blob and buffer lacks some context, so the git_diff_file parameters to the callbacks will be faked a la the rules for git_diff_blobs().

Passing NULL for old_blob will be treated as an empty blob (i.e. the file_cb will be invoked with GIT_DELTA_ADDED and the diff will be the entire content of the buffer added). Passing NULL to the buffer will do the reverse, with GIT_DELTA_REMOVED and blob content removed.
