Someone can tell me why this piece of code doesn't work?
#include<stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <sys/sysctl.h>
#include <sys/time.h>
#include <net/if.h>
#include <net/if_mib.h>
int main(void) {
int mib[5], *count;
mib[0]=CTL_NET;
mib[1]=PF_LINK;
mib[2]=NETLINK_GENERIC;
mib[3]=IFMIB_SYSTEM;
mib[4]=IFMIB_IFCOUNT;
sysctl(mib, 5, count, sizeof(int),(void *)NULL, NULL);
printf("count: %d\n",*count);
}
I'm searching the number of interfaces available.
thanks.
