I'm trying to interface to a C function:

and getting the error:
Error: function <src>.textAttrN without 'this' cannot be const
Please advise as to what I'm doing wrong?! :-(
without the parens, 'const' means that the function doesn't
mutate the state of the object or of the struct it's declared in.
So it's meaningless for a global function.
To avoid the confusion, take the habit to put 'const' at the
right of the function declaration when it's related to a member
function and only to the left when it's related to the type, and
then to the left <=> always with parens.
