Employee Program problem only part

[mkarki2]

I am doing a likned list program in C.
I am not really good at it and just started. But I am stuck how to pass structure in the function correctly.

this is the driver file

#ifndef DRIVER_C
#define DRIVER_C
#include "constants.c"
int main(void)
{
  struct employee *startPtr = NULL;
 
  FILE *fileptr= fopen("hw3Employees.dat","r");
  employee only;
 
  getvalues( only, *fileptr);
 
  //insert(&startPtr, fname[],lname[],middle[],id,title[],balance);
    return 0;
}
//void insert(struct employee **sPtr, char fname[],char lname[],char middle[],int id,char title[], int balance)
//{
//return;
//}
 
void getvalues(struct employee *only,FILE ** fileptr)
{
 
    fscanf(*fileptr,"%s%s%s%d%s%d%x",only.fname,
                only.lname,
                only.mname,
                &(only.id),
                only.title,
            &(only.Balance);
        printf("%s %s   %s    %d    %s    %d  %x\n",only.fname,
            only.lname,
            only.mname,
            only.id,
            only.title,
        only.Balance);
return;
 
}
#endif
 

and the constants file

#ifndef CONSTANTS_C
#define CONSTANTS_C
#include <stdio.h>
#include <stdlib.h>
#define ARRAY_SIZE 5
#define ZEROI 0
#define ZEROD 0.00
#define NAME_LEN 30
 
typedef struct {
        char fname[NAME_LEN];  //first name
        char lname[NAME_LEN];  //last name
        char mname[2];
        int id;
        char title[NAME_LEN];
        int Balance;
        struct employee *nextPtr;
}employee;
 
void insert(struct employee **sPtr, char[],char[],char[],int,char[],int);
void getvalues(struct employee*,FILE **);
#endif
 

...I am currently working on the getvalues and it does not seem to be working? Can anyone help?
