DESCRIPTION    [Toc]    [Back]

       The if_indextoname() function maps an interface index number
 to its corresponding interface name.

RETURN VALUES    [Toc]    [Back]

       Upon  successful conversion, the if_indextoname() function
       returns the value specified in the ifname parameter, which
       points  the  buffer  that now contains the interface name.
       If no interface name corresponds to the index, it  returns
       a NULL pointer.
