How do I modify a pointer that has been passed into a function in C?

Question

So, I have some code, kind of like the following, to add a struct to a list of structs:

void barPush(BarList * list,Bar * bar)
{
    // if there is no move t         


        

Answer 1

Yes, you have to pass in a pointer to the pointer. C passes arguments by value, not by reference.
