How do I pass this function if

int &pos(void) - returns the element at "position" by reference

my method in class definition:
int &pos(void):

my function is

int dequeint::&pos(void)
               return CurrPos->x;
                NodeValueType dequeint::front()
                     return headi->x;

but i get this compiler error expected unqualified-id before "&" token
Many thanks!

& applies to the type, not the name:

int& dequeint::pos(void)
