But when I try to write into such an array inside a block, I get a > compile error, "cannot access __block variable of array type inside block." void foo() { __block char barfy[100]; ^() { char b = barfy[0]; <<<< error: cannot access __block variable of array type inside block b = b; }; } void bar() { __block struct angus { char barfy[100]; } kangus; ^() { char b = kangus.barfy[0]; // compiles fine b = b; }; } The reason being that a Block_copy() or [block copy] will cause the __block variables to be moved to the heap and, thus, the compiler must know the exact size of all variables to be copied when emitting the copy helper. b.bum _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
