* EXAMPLE
|
|
* Setting hoplimit for all interfaces:
|
|
* int hoplimit = 32;
|
|
* name[0] = IP_CTL_NET;
|
|
* name[1] = IP_AF_INET6;
|
|
* name[2] = IP_IPPROTO_IPV6;
|
|
* name[3] = IP_IPV6CTL_ND_CURHOPLIMIT;
|
|
*
|
|
* ipcom_sysctl(name, 4, NULL, NULL, &hoplimit, sizeof(hoplimit));
|
|
*
|
|
* Setting hoplimit for a specific interface (index = 1):
|
|
* int hoplimit = 32;
|
|
* name[0] = IP_CTL_NET;
|
|
* name[1] = IP_AF_INET6;
|
|
* name[2] = IP_IPPROTO_IPV6;
|
|
* name[3] = IP_IPV6CTL_ND_CURHOPLIMIT;
|
|
* name[4] = 1;
|
|
*
|
|
* ipcom_sysctl(name, 5, NULL, NULL, &hoplimit, sizeof(hoplimit));
|
|
*
|
|
* RETURNS:
|
|
* 0 for success or -1 for failure.
