Dirty little secret: every ivar access on 64-bit is already indirected through the runtime. Otherwise the runtime couldn't support non-fragile instance variables. :) You could theoretically get better performance if your instance variable were a pointer-to-struct. But if your way is sufficiently performant, stick with it. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
