How to pass a typedef struct to function?

[difficult.name]

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?

#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.

#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
{
   //........
}
