Hi,
I try to run a really simple example. But it doesn't work and I'm very
despaired.
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/mman.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <errno.h>
#include <sched.h>
#include <netdb.h>
#include <arpa/inet.h>
#include <netinet/in.h>
#include <rtnet.h>
#include <rtai_serial.h>
#include <rtai_lxrt.h>
static struct sockaddr_in local_addr;
static struct sockaddr_in server_addr;
int main(int argc, char **argv) {
setuid(0);
system("ifconfig eth0 down");
system("/sbin/insmod /usr/realtime/modules/rtai_hal.ko");
system("/sbin/insmod /usr/realtime/modules/rtai_lxrt.ko");
system("/sbin/insmod /usr/realtime/modules/rtai_sem.ko");
system("/sbin/insmod /usr/realtime/modules/rtai_rtdm.ko");
system("/sbin/insmod /lib/modules/2.6.31.8-rtai-1v/rtnet.ko");
system("/sbin/insmod /lib/modules/2.6.31.8-rtai-1v/rtipv4.ko");
system("/sbin/insmod /lib/modules/2.6.31.8-rtai-1v/rtpacket.ko");
system("/sbin/insmod /lib/modules/2.6.31.8-rtai-1v/rt_loopback.ko");
system("/sbin/insmod /lib/modules/2.6.31.8-rtai-1v/rt_8139too.ko");
system("/usr/local/rtnet/sbin/rtroute add 192.168.180.1 00:10:A7:1E:DC:7E
dev rteth0");
int sockfd = 0;
int ret = 0;
int res;
RTIME period;
RT_TASK *task;
memset(&local_addr, 0, sizeof(struct sockaddr_in));
memset(&server_addr, 0, sizeof(struct sockaddr_in));
local_addr.sin_family = AF_INET;
local_addr.sin_addr.s_addr = INADDR_ANY;
local_addr.sin_port = htons(atoi("8080"));
server_addr.sin_family = AF_INET;
server_addr.sin_addr.s_addr = inet_addr("192.168.180.2");
server_addr.sin_port = htons(atoi("8080"));
sockfd = rt_dev_socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP);
printf("error: %i\n", errno);
printf("Sockfd: %i\n", sockfd);
return 0;
}
I open this file with eclipse and let it run (I do nothing befor; like
module-load or something else). The printfs give me the following back:
error: 38
Sockfd: -97
Any idea?
Regards,
Franz

I don't know precisely how many people use RTnet with RTAI these days.
Based on the feedback, I would say it's a moderate number.
I'm doing RTnet development over Xenomai for those 5 years now (both
professionally and privately). Therefore, fixes and enhancements related
to any RTAI use depend on contributions.
