using struct elements in function that is in another source file

New to learning c and I am having difficulties with writing a function in another source file that uses struct variables from the first source file.

basically I need to create a bubblesort function in another file to be used in my driver

this is what i am trying to do

driver.c

#include<stdio.h>
#include<stdlib.h>
#include<sort.c>
typedef struct iorb {
        int base_pri;
        struct iorb *link;
        char filler[100];
} IORB;

int main(){
sort();
}

sort.h

void sortList(IORB * head, int(*prio)(int));

sort.c

void sortList(IORB * head, int(*prio)(int)){
// do stuff
}

but i get this error: unknown type IORB in the sort function.

how can pass the IORB to the function ?

Updated code after trying the answer: driver.c

#include<stdio.h>
#include<stdlib.h>
#include "sort.h"
#include "iorb.h"
  //removed the typedef in the driver

iorb.h

#ifndef IORB_H
#define IORB_H

typedef struct iorb {
        int base_pri;
        struct iorb *link;
        char filler[100];
} IORB;

#endif

sort.h

#ifndef SORT_H_
#define SORT_H_


void sortList(IORB * head, int(*prio)(int));

#endif

sort.c

#include "sort.h"
#include<stdlib.h>
#include<stdio.h>
#include "iorb.h"


void sortList(IORB * head, int(*prio)(int)){
//do stuff
}
