 This is how you read a blob (actually, not only a blob, but any type of
-object).  To know how the function `read_object_with_reference()` actually
+object).  To know how the function `odb_read_object_peeled()` actually
 works, find the source code for it (something like `git grep
 read_object_with | grep ":[a-z]"` in the Git repository), and read
 the source.
