KDK_NET_GET_HOSTS(3)       Library Functions Manual       KDK_NET_GET_HOSTS(3)

NAME
       kdk_net_get_hosts - <?><?>hosts<?><?>

SYNOPSIS
       #include <libkynetinfo.h>

       extern char* kdk_net_get_hosts();

       Link with -lkynetinfo.

Detailed Description
       The main function of the interface is to obtain the hosts
       configuration.

RETURN VALUE
       On success, returns the hosts configuration of type char *; The
       returned string needs to be released by free

       On error, return NULL.

       #include "libkynetinfo.h"
