sendto: Invalid argument netbsd

[quant]

hi all,
I've a program which worked on linux, but after porting on netbsd I take this error..
sent=sendto(sock, buf, buf_siz, 0, (struct sockaddr *) &sin, sizeof(sin));
why?
I did verifying of values which's take function sendto, but they allright.
sent receive -1

Can you post the error. Thanks.

sendto returns -1
at that time it code works very well

	if((raw = socket(PF_INET, SOCK_RAW, PPROTO_TCP))== -1) {
                perror("Error creating raw socket: ");
                return 0;
        }

what is errno set to?

sendto: Invalid argument

In first time I use 1 without my_send, but I need doing it from another function like my_send.

struct sockaddr_in sin; //1
//struct sockaddr_in *sin; //2
malloc(sizeof(struct sockaddr_in));
//i'll take "error: request for member 'sin_family' in something not a structure or union ", therefore I'll use 2..., but I've got segfalt
sin.sin_family = AF_INET;
//sin->sin_family = AF_INET; //2
//Segmentation fault 2
my_send(socket,buffer,&sin); //1
sent=sendto(sock, buf, buf_siz, 0, (struct sockaddr *) &sin, sizeof(sin));
if(sent < 0) {
perror("sendto");
exit(1);
}
void my_send(int s,const char *buf, const struct sockaddr *addr){
int buflen = strlen(buf);
int sent =0;
sent = sendto(s, buf, buflen, 0, (struct sockaddr *)addr,sizeof(addr));
if(sent<0){
perror("sendto");
exit(1);
}// sendto: invalid argument 1 Without my_send function it's works very well, i think what it because somewhere I did a mistake.
}

sizeof(addr) in my_send() is the size of a pointer. You want to pass in the size to my_send().

[quant]

ok, I fixit
but I've got another problem. There I did post two different methods which's I tried/

struct sockaddr_in *sin;
sin->sin_family = AF_INET;
my_send(socket,buffer,sin);
//warning: passing argument 3 of 'my_send' from incompatible pointer type
struct sockaddr_in sin;
sin.sin_family = AF_INET;
my_send(socket,buffer,&sin);

But I seems, what it similar of this...

int number;
int *tommy;
tommy = &number;
