invalid argument in sendto
anyone care to tell me why? code compiles fine but when trying to run the send to gives me an Invalid Argument in the errno
int sock_fd;
AARP_Packet* tempAARP = (AARP_Packet*) malloc(sizeof(AARP_Packet));
/*how I initialize the aarp_sockaddr port is defined but not shown here*/
bzero((char *)&aarp_sockaddr,sizeof(aarp_sockaddr));
aarp_sockaddr.sin_family = AF_INET;
bcopy(hp->h_addr_list[0], (char *)&aarp_sockaddr.sin_addr,hp->h_length);
aarp_sockaddr.sin_port = htons(port);
flag = sendto(sock_fd, (void*)tempAARP, sizeof(AARP_Packet), 0, (struct sockaddr *)&aarp_sockaddr, sizeof(aarp_sockaddr));
if (flag == -1){
perror("Error: Sending AARP Packet failed \n");
close(sock_fd);
exit(1);
}

Your sample shows sock_fd is never initialized, or opened, so likely sendto is complaining of a bad descriptor.

I actually did, just forgot to put it above
/* create socket */
sock_fd = socket(PF_INET,SOCK_DGRAM,0);
if (sock_fd < 0)
{
perror("Error: Socket creation failed\n");
exit(1);
}
