Hi All,

     I am working on dhcpd api by using dhcpctl.h. I am trying to assign 
static IPs for machines when its hostname and mac-address was provided. 
I have tried so far. When I tried to add a new host detail. The 
mac-address alone not assigned properly. Some junk value it is giving. 
The code what I have used is below.

     dhcpctl_data_string macaddrstring = NULL;

     memset (&macaddrstring, 0, sizeof macaddrstring);

     omapi_data_string_new (&macaddrstring, 16, MDL);

     memcpy(macaddrstring->value, "00:0c:26:22:bf:c3", 16);

     status = dhcpctl_set_value (host, macaddrstring, "hardware-address");

I am seeing following value in lease file.

host testomapihost {
   hardware ethernet 31:30:30:3a:30:63:3a:32:36:3a:32:32:3a:62:66:3a;

Whether like ip address ( example provided in man page)  we need to 
convert mac-address also to any valid format. We can't pass the value 
just like string. What I am doing wrong. Any help will be grateful for me.
