[ECOS] Unable to add route using routing socket

[aditya veer singh]

Hi,

I am using ecos taken from CVS branch of FEB 2006.
I want to add a route to BSD TCP/IP stacks IP route table 
using routing sockets.
I have written the below code:

        u_int32_t g,m,d;
        int routes;
        struct{
                struct rt_msghdr        hdr;
                struct sockaddr_in      dst;
                struct sockaddr_in      gway;
                struct sockaddr_in      mask;
        }rtmsg;

        if((routes = socket(PF_ROUTE, SOCK_RAW, AF_INET) < 0)){
                diag_printf("\nError route socket");
        }

        memset(&rtmsg, 0, sizeof(rtmsg));

        rtmsg.hdr.rtm_msglen = sizeof(rtmsg);
        rtmsg.hdr.rtm_version = RTM_VERSION;
        rtmsg.hdr.rtm_type = RTM_ADD;
        rtmsg.hdr.rtm_addrs = RTA_DST|RTA_GATEWAY|RTA_NETMASK;
        rtmsg.hdr.rtm_flags = RTF_UP|RTF_HOST|RTF_STATIC;
                
        rtmsg.dst.sin_len = sizeof(rtmsg.dst);
        rtmsg.dst.sin_family = AF_INET;
        inet_pton(AF_INET, "192.168.9.55",(char *)&rtmsg.dst.sin_addr);

        rtmsg.gway.sin_len = sizeof(rtmsg.gway);
        rtmsg.gway.sin_family = AF_INET;
        inet_pton(AF_INET, "192.168.7.43",(char *)&rtmsg.gway.sin_addr);

        rtmsg.mask.sin_len = sizeof(rtmsg.mask);
        rtmsg.mask.sin_family = AF_INET;
        inet_pton(AF_INET, "255.255.255.255",(char *)&rtmsg.mask.sin_addr);

        if(write (routes, &rtmsg, sizeof(rtmsg)) < 0){
                perror("write");
        }

On executing it I get error in write "Bad file handle".
What needs to be done correct it?

Regards,
Aditya
