RESOLVED :how to parse a matrix of structure by reference in C into a function?

I'm writing a algorithm which permits to resolve "Hashiwo Kakero" exo, so i defined all bridge as a couple of value example :

bridge1{
    x_coordonnate : 5;
    y_coorodonnate : 12;
    importance : 17;
    degre_8: 0;
} 


void initialiser_pieces(Piece *piece,int degre,int i , int j){
    piece->coordonnees_x = i;
    piece->coordonnees_y = j;
    piece->degre = degre;
    if(degre == 8)
        piece->degre_8 = 1;
    else
        piece->degre_8 = 0;
}


    void fonction_check8liaisons(Piece *puzzle[totallignepuzzle],int ligne, int colonne){
int i_local, j_local;
for (i_local = 0; i_local < ligne; i_local ++){
    for (j_local = 0; j_local < colonne; j_local ++){

        if(&puzzle[i][j].degre  == 8){

        // can't modify attribute of my matrice , get exception here
            puzzle[i][j] = 50;

        }
    }
    }
}

Here is where i define PuzzleDeck

int main(){
...
int totallignepuzzle = 2,totalcolonnepuzzle = 2;


Piece puzzledeck[totallignepuzzle][totalcolonnepuzzle];
// remplissage du puzzle
for(i = 0; i < totallignepuzzle; i++){
    for(j = 0; j < totalcolonnepuzzle; j++){
        printf("nn Veuillez saisir le degré de la piece de coordonnées (x = %d, y =%d)",i+1,j+1);
        scanf("%d",&ledegre);
        initialiser_pieces(&puzzledeck[i][j],ledegre,i,j);
    }
}

 fonction_check8liaisons(&puzzledeck,totallignepuzzle, totalcolonnepuzzle);


}

i will use many function according for all rules and i would like to know how pass a matrix of structure by reference in a function

Could you help me to know how pass a matrix of structure by reference in a function ?

i tried this :

with

but got an exception , could you help me please ?
