How to get Processor information

Post by David Weatherwa » Fri, 09 Feb 2001 01:05:25



I tried this site, and the perfpmr for 4.3.3.0 says page not found

Any other place to find this?

Thanks

1. getting the network interface information and default gateway information ??

hi,
  iam trying to get the network interface information and the default
information.After doing some googling i found out the relevant
structures and the ioctl calls for getting the interfaces information(
i suppose i have all that right).
struct ifconf(and using the ioctl SIOCGIFCONF).
there is another structure
struct ifreq
but i dont think i need that one.

Now how do i do to get the interface address(aliases also).i have
written a small program, but dont know where iam going wrong.the code
is

#include <stdio.h>
#include <stdlib.h>
#include <sys/ioctl.h>
#include <sys/types.h>
#include <net/if.h>
#include <netinet/in.h>

int
main(int argc, char* argv[])
{
    struct ifconf ifc;
    struct ifreq *ifr;
    struct sockaddr_in *sin;
    char buf[128];

    if ((s = socket(AF_INET, SOCK_DGRAM, 0)) < 0) {
        perror("socket");
        return 1;
    }

    ifc.ifc_buf = buf;
    ifc.ifc_len = sizeof(buf);
    if (ioctl(s, SIOCGIFCONF, &ifc) < 0) {
        perror("ioctl SIOCGIFCONF");
        return 1;
    }

    ifc.ifc_len /= sizeof(struct ifreq);
    for (i=0; i<ifc.ifc_len; i++) {
        ifr = (struct ifreq *) &ifc.ifc_req[i];
        sin = (struct sockaddr_in *) &ifr->ifr_addr;
        printf("%s \n",sin->sin_addr);
        }
    }
    return 0;

And how can i get the default gateway address within my program.

any help will be highly appreciated.

thanks
