casting - warning: assignment makes integer from pointer without a cast. whats wrong? -

i got warning "warning: assignment makes integer pointer without cast"! want figure out mean? , need change in fucntion create_rectangle..... thank you. appreciated

struct point {         int x;         int y;     };      struct rectangle {         struct point upperleft;         struct point lowerright;         char label[namesize + 1];     }; 

and code:

struct rectangle *create_rectangle(struct point ul, struct point lr,                                    char *label) {      struct rectangle *r = malloc(sizeof(struct rectangle));       r->upperleft=ul;     r->lowerright=lr;     r->label[namesize+1]= strncpy(r->label,label,namesize);    //here warning       r->label[namesize] = '\0';      return r; } 

strncpy returns pointer assigning char. (actually, assigning illegal address r->label[namesize+1] beyond bounds of array.)

it should

struct rectangle *create_rectangle(struct point ul, struct point lr,                                    char *label) {      struct rectangle *r = malloc(sizeof(struct rectangle));       r->upperleft=ul;     r->lowerright=lr;     strncpy(r->label,label,namesize);     r->label[namesize] = '\0';      return r; }
