Function Documentation
◆ flnl_result_alloc()
◆ flnl_result_put()
◆ flnl_result_alloc_cache()
| struct nl_cache * flnl_result_alloc_cache | ( | void | ) |
Allocate lookup result cache.
Allocates a new lookup result cache and initializes it properly.
- Note
- Free the memory after usage using nl_cache_destroy_and_free().
- Returns
- Newly allocated cache or NULL if an error occured.

Builds a netlink request message to do a lookup.
- Parameters
-
req Requested match. flags additional netlink message flags result Result pointer
Builds a new netlink message requesting a change of link attributes. The netlink message header isn't fully equipped with all relevant fields and must be sent out via nl_send_auto_complete() or supplemented as needed. old must point to a link currently configured in the kernel and tmpl must contain the attributes to be changed set via rtnl_link_set_* functions.
- Returns
- 0 on success or a negative error code.

Perform FIB Lookup.
- Parameters
-
sk Netlink socket. req Lookup request object. cache Cache for result.
Builds a netlink message to request a FIB lookup, waits for the reply and adds the result to the specified cache.
- Returns
- 0 on success or a negative error code.
