They can, actually; there is no problem with this at the ABI/runtime level. I think what you mean is that most libraries/frameworks don't make guarantees about properly handling exceptions thrown into them, i.e. from a call into external code. Some C++ libraries do guarantee this (especially libc++), and even without guarantees a typical C++ lib using RAII will be relatively safe, but Objective-C code usually isn't written to be exception-safe, and C code of course can't be. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
