my error is storage class specified for parameter

i need a bit of help. i have the following code

Code:

#ifndef PERSON_H_INCLUDED
#define PERSON_H_INCLUDED
#include <stdio.h>
#include <stdlib.h>

typedef struct nod
{
  char name[50];
  unsigned int birthdate;
  char address[100];
  char cnp[14];
    struct nod *next;
    struct nod *prev;
} PersonEntryT;


typedef struct
{
        int size;
    PersonEntryT *last;
    PersonEntryT *first;
    }ListDT;


extern ListDT *createDList();
extern PersonEntryT *createDNode( char name[], unsigned int birthdate, char address[], char cnp[]  );
extern PersonEntryT *insertDDepOnKey(char a[], PersonEntryT  *p, ListDT *L);
extern PersonEntryT *findDyear(  int key,  ListDT *L);
extern PersonEntryT *findDcnp(char key[],  ListDT *L);
extern char *printDItem(PersonEntryT  *pItem);
extern PersonEntryT *insertDAtEnd(PersonEntryT *p, ListDT *L);
extern void deleteDItem (void *pItem);
extern int keyCmp(int a, int b);


#endif // PERSON_H_INCLUDED

after compiling i get the following error serie:

Code:

error: storage class specified for parameter 'insertDDepOnKey' 
error: storage class specified for parameter 'findDyear' 
error: storage class specified for parameter 'findDcnp' 
error: storage class specified for parameter 'printDitem' 
error: storage class specified for parameter 'insertDAtEnd' 
error: storage class specified for parameter 'deleteDItem' 
error: storage class specified for parameter 'keyCmp'

what is the problem?
i saw that there was another person who had the same problem, i checked all the possible remedees that u suggested him, but i didn't find any missing semicolon or parathesis. Also this is my only header file in the program, the parameters are checked, their type and order is correct. Thought i bet the problem is with them .
Thank u for any help, suggestion.(PS i would need an urgent respons)

Sorry, but I cannot duplicate those errors with your sample code.

My only explanation is that the closing paren on the end of this line must not actually be there:

Code:

extern PersonEntryT *createDNode( char name[], unsigned int birthdate, char address[], char cnp[]  );

The following errors are probably due to the "extern" keyword. If that paren was missing, the following prototypes would be interpretted as parameters, and extern is illegal in that context.

Are you sure you've posted the exact code you are using? Because those semicolons should also have thrown out some errors if they were found inside a parameter list.

hey u were right!!!thank u sooo much!! the extern command was the problem.
thank u!!!!

Huh? The extern is redundant here, but the point is that a missing closing parenthesis could be the problem.

i checked several times, seems like no missing paranthesis to me, but i may be mistaking. It works now though, so thanks for your time brewbuck and laserlight
