* Description:
|
|
* Traverse the routing table
|
|
*
|
|
* Input Parameters:
|
|
* handler - Will be called for each route in the routing table.
|
|
* arg - An arbitrary value that will be passed to the handler.
|
|
*
|
|
* Returned Value:
|
|
* Zero (OK) returned if the entire table was search. A negated errno
|
|
* value will be returned in the event of a failure. Handlers may also
|
|
* terminate the search early with any non-zero, non-negative value.
