This also makes FIND-SELECTOR +return NIL for unknown selectors on the NeXT runtime, so compile-time +warnings about unknown methods are possible there now. The latter +relies on sel_isMapped, whose semantics are not entirely clear to me. +On the one hand, Apple's reference manual states: “You can use this +function to determine whether a given address is a valid selector,” +which I interpret as meaning that it takes a selector pointer as an +argument, not a string. On the other hand, in the preceding section, +the same document states: “You can still use the sel_isMapped function +to determine whether a method name is mapped to a selector.” + +So if I have two strings that aren't the same under POINTER-EQ, but that +both name the same valid selector that is registered with the runtime, +like "self", say, does sel_isMapped work reliably in this case? I'm not +sure. + +On another note, I wonder what the difference between +sel_get_uid/sel_getUid and sel_register_name/sel_registerName might be. +They seem to do the same thing. + +Maybe this whole #ifdef mess isn't even strictly necessary, anyway. I +could just copy objc-gnu2next.h from the GNUstep project (LGPLv3, so the +licensing is fine). + +http://svn.gna.org/svn/gnustep/libs/base/trunk/Headers/Additions/GNUstepBase/objc-gnu2next.h + + + * 2007-10-04, 17:27:02 CEST ** `char' Does Actually Indicate a Char, Sometimes |
