Detailed Description

Result of a lookup in the extended table.

Each program has an extended table to store 1M records by keys of TABLE_EX_KEY_SIZE bytes, each record holding a value of TABLE_EX_VALUE_SIZE bytes. Extended table may be slower than basic table.

Key of zero bytes only is reserved and forbidden. Value access is not guaranteed to be atomic.

Key mut have at least one bit set in bytes 8..15, so a four-byte IPv4 address is not a valid key, but struct NetAddr is, due to its layout.

Last update time is maintained for each record and stale records are purged, so there is no removal operation. To keep a record in the table, call table_ex_get() or table_ex_put().

The documentation for this struct was generated from the following file:
