It generally doesn't, unless you apply const to the underlying type, and
not just the pointer.

IE you say you have a pointer to a constant piece of memory, not a
constant pointer to a piece of memory.


But... tree is a pointer to "union tree_node" , isn't it? perhaps it
is that "const tree" is not the same as " const union tree_node * " ?

(btw, thanks for taking the time to clarify my doubts...)
