KDK_NET_GET_NETMASK(3)     Library Functions Manual     KDK_NET_GET_NETMASK(3)

NAME
       kdk_net_get_netmask -
       <?><?><?>kdk_net_get_iptable_rules<?><?><?><?><?><?><?><?><?><?><?>

SYNOPSIS
       #include <libkynetinfo.h>

       extern void kdk_net_get_netmask(IN const char *nc, OUT char *mask);

       Link with -lkynetinfo.

Detailed Description
       The main function of the interface is to obtain subnet mask
       information.

       The argument nc is the name of the NIC, such as "eno1".

       The argument mask is the subnet mask information.

RETURN VALUE
       No return value
