- * From RFC 2553:
- *
- * 4.3 Return All Interface Names and Indexes
- *
- *    The if_nameindex structure holds the information about a single
- *    interface and is defined as a result of including the <net/if.h>
- *    header.
- *
- *       struct if_nameindex {
- *         unsigned int   if_index;
- *         char          *if_name;
- *       };
- *
- *    The final function returns an array of if_nameindex structures, one
- *    structure per interface.
- *
- *       struct if_nameindex  *if_nameindex(void);
- *
- *    The end of the array of structures is indicated by a structure with
- *    an if_index of 0 and an if_name of NULL.  The function returns a NULL
- *    pointer upon an error, and would set errno to the appropriate value.
- *
- *    The memory used for this array of structures along with the interface
- *    names pointed to by the if_name members is obtained dynamically.
- *    This memory is freed by the next function.
- *
- * 4.4.  Free Memory
- *
- *    The following function frees the dynamic memory that was allocated by
- *    if_nameindex().
- *
- *        #include <net/if.h>
- *
- *        void  if_freenameindex(struct if_nameindex *ptr);
- *
- *    The argument to this function must be a pointer that was returned by
- *    if_nameindex().
