How to pass a typedef struct to function?

Hi, I'm trying to understand how to pass typedef structures to a function. The following is how I'm trying to do it, but it doesn't work (parse errors). What am I doing wrong?

Code:

---

#include <stdio.h>

void func(test, test); // parameter name warning occurs here

int main()
{
  typedef struct{
      int a, b, c;
  } test;
  test here, there;

  //.........

  func(here, there);

  return 0;
}

void func(test here, test there) // parse error occurs here
{
  //........
}

---

declare your structure outside of the function.

Code:

---

#include <stdio.h>

typedef struct{
      int a, b, c;
  } test;

void func(test, test); // parameter name warning occurs here

int main()
{
 
  test here, there;

  //.........

  func(here, there);

  return 0;
}

void func(test here, test there) // parse error occurs here
{
  //........
}

That fixed it, thanks!
