Example #1

int main(int argc, char *argv[])
{
    int sock;
    char* msg;
    struct sockaddr_in saddr;

	fprintf(stderr, "usage: dgsend host port 'message'\n");
	exit(1);
    }

    if ((sock = make_dgram_client_socket()) == -1)
    {
	oops("cannot make socket", 2);
    }

    if (make_internet_address(argv[1], atoi(argv[2]), &saddr) == -1)
    {
	oops("make addr", 4);
    }

    if (sendto(sock, msg, strlen(msg), 0, (struct sockaddr*)&saddr, sizeof(saddr)) == -1)
    {
	oops("sendto failed", 3);
    }
    return 0;
}
