Hi, I am wondering if I may compare pointers with < that have been created using different calls of malloc. The C standard does not allow this (inequalities are only allowed for pointers into the same structure) to allow for some cheapskate sort of comparison in segmented architectures. Now of course being able to _sort_ pointers also allows to _collate_ them. It totally does not matter just _what_ their ordering relation is as long as it yields to a sorting function (namely obeys some basic relations). The question is whether this kind of undefined behavior (which almost never is implemented in unexpected ways) is frowned upon in the Git codebase or not. -- David Kastrup -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
