C++ ::  Read From File And Insert Into Linked List

I have a program and function i'm having an issue understanding. Here is what it's doing in the main.

int main() {
orderedLinkedList<MemberDO> memberList;
MemberDO::readFromFile("Member.dat", memberList);
return 0;
}

So it is creating a linked list object using the MemberDO class type which has a int, string, char and double. Then it will call the readFromFile static function in the MemberDO. So this is where my problem is I have this function

void MemberDO::readFromFile(char *fname, orderedLinkedList<MemberDO>& list) {
}

How do I read in each individual data member from the input then create a new MemberDO object and insert the objects into the linked list specified in the second argument list?

Here is the MemberDO class declarations

class MemberDO {
private:
int key;
string lastName;
char firstInitial;
double dues;
