calling a function with a pointer to a struct

I am trying to wrap my noodle around the whole pointer concept here. I want call the function fun1 with a pointer. What syntax do I use? What I doing wrong?

I get this error when I try to compile

Code:

---

boohoo.cpp: IN function 'int main(int, char**)':
boohoo.cpp 21: error: expected primary-expression before ')' token

---

Code:

---


#include <iostream>


using namespace std;

struct myStruct
{
        long * stuff1;
        long  stuff2;
        long  stuff3;
};

void fun1(myStruct* workplz);

int main(int argc, char* argv[])
        {
       
        myStruct workplz;

       
        fun1(workplz*);
       
        }//end main
       
void fun1 (myStruct* workplz)
{
        cout<<"it works."<<endl;
}

any help would be great

Code:

---

fun1(&workplz);
