I can't figure out why this code won't bind to 127.0.0.1 on FreeBSD. I get
an error "Can't assign requested address".

int main() {
int sock;
struct sockaddr_in dp;
unsigned long bind_to_addr = inet_addr("127.0.0.1");
sock = socket(PF_INET, SOCK_STREAM, IPPROTO_TCP);
if(sock < 0) {
printf("Error socket : %s\n", strerror(errno));
return -1;
}
dp.sin_family = AF_INET;
dp.sin_addr.s_addr = htonl(bind_to_addr);
dp.sin_port = htons(1234);
if(bind(sock, (struct sockaddr*)&dp, sizeof(struct sockaddr_in))!=0)
{
printf("Bind failed : %s\n", strerror(errno));
} else {
printf("Bind success\n");
}
}
