Yup. Should do.

for (int index = 0; index < 5; index++) {
	// index variable only defined here
}

// index variable no longer defined here.


(The old 'for' scoping meant that index was valid after the for loop as
well, which leads to problems when you type something like:

for (int i = 0; i < 5; i++) { ... }
for (int i = 0; i < 5; i++) { ... }

Because it moans about i being redefined.)

Use

nodebufstat->figure

or

(*nodebufstat).figure

The problem is that the '.' binds more strongly than the '*'
