I can never keep these straight since I keep forgetting the exact rules around pointer type qualifiers, so for my own reference:

const X * foo;    // Cannot change what is being pointed at, can change the pointer
    foo = &bar;   // Allowed
    *foo = bar;   // Not Allowed

X const * foo;    // Equivalent to the above

X * const foo;    // Cannot change the pointer value, can change what is pointed at
    foo = &bar;   // Not Allowed
    *foo = bar;   // Allowed

const X * const foo; // Cannot change either the pointer value or the target
    foo = &bar;   // Not Allowed
    *foo = bar;   // Not Allowed
