Conversion from 'void *' to 'vector

I am casting a vector pointer as a void pointer to a function. In that function, how to I cast it to a vector pointer?

in main

vector<int *> foo;
function(&foo);

in function
function(void *bar){
    auto temp = bar; // what replaces auto or what should bar be cast to?
    temp.pushback(something);
}

I hope I have not mangled the terminology, any opinion helps!
