Here's the files , i want to use includes :
primitives.h:

```
#ifndef PRIMITIVES_H_
#define PRIMITIVES_H_
#include "bloc.h"
#endif

```

primitives.c

```
#include "primitives.h"
Bloc_T creat2(char* ,BT_T); 

Bloc_T creat2(char* nomfic ,BT_T typefic)
{
Bloc_T Nouv_Bloc;
setTitreMeta(Nouv_Bloc.infosFic,nomfic);
Nouv_Bloc.typeBloc= typefic; 
return Nouv_Bloc;
}

```

bloc.h:

```
#ifndef STRUCTURES_H_INCLUDED
#define STRUCTURES_H_INCLUDED

// BIBLIOTHEQUES STANDARDS
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <fcntl.h>
#include <sys/stat.h>
#include <sys/types.h>
#include <string.h>

// MACROS
#define TAILLE_BD 20
#define NBR_BLOC_PAR_FIC 5

struct Metadonnees
{
char* nomFic;

};
// Alias
    typedef struct Metadonnees MD_T;

enum blocType{
    BV,BD,BREP,BI
};

```

// Alias
 typedef enum blocType BT\_T;

```
struct Bloc
{
    BT_T typeBloc;
    int** adressesInodes;  //tableau des adresses des BD (BI ou BRep)
    MD_T infosFic;
    char* data;  //bloc données
    char** nomsFic; // pour les BRep
    // bloc vide: tout à null
};
// Alias
typedef struct Bloc Bloc_T;

```

I get this warning: 

```
primitives.c:8:2: attention : implicit declaration of function ‘setTitreMeta’ [-Wimplicit-function-declaration]

```

But i have defined it in bloc.c.

Edit: Bloc.c
 #include "bloc.h"

```
void setTitreMeta(MD_T , char* );
void setTitreMeta(MD_T meta, char* titre)
{
    int taille = strlen(titre);
    meta.nomFic=(char*)malloc(sizeof(char)*taille);
    strcpy(meta.nomFic,titre);
    printf("Nom du fichier: %s\n",meta.nomFic);
}

```

I'm defining it in bloc.c but it shows me the warning .. where should I define it ( declare it )?
