 /**
+ * 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.
+ *
+ * @param out The generated patch; NULL on error
+ * @param old_buffer Raw data for old side of diff, or NULL for empty
+ * @param old_len Length of the raw data for old side of the diff
+ * @param old_as_path Treat old buffer as if it had this filename; can be NULL
+ * @param new_buffer Raw data for new side of diff, or NULL for empty
+ * @param new_len Length of raw data for new side of diff
+ * @param new_as_path Treat buffer as if it had this filename; can be NULL
+ * @param opts Options for diff, or NULL for default options
+ * @return 0 on success or error code < 0
