No, you made that one up :) As we considered that it would be common to want to specify the type of an expression, we thought it would be tiresome to have to put eg expression int x. So you can just say int x. The downside is that people write identifer x; and then don't understand the error message, because any misspelled metavariable kind is considered to be a type name. julia > But then I don't find (or maybe don't parse too well) > the coccinelle documentation that specifies these > type relationships. > > cheers, Joe > > > -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
