Detailed Description

Structure holds data common to TCP and UDP connections.

Field Documentation

cid

uint64_t conn_s::cid

Connection ID. While it is set for all connections, it is only used for TCP connections.

[union]

union { ... } conn_s::conn

Holds either TCP or UDP specific data depending on connection protocol.

fd

int conn_s::fd

Socket descriptor this connection is associated with.

gen_q_handle

struct conn_s* conn_s::gen_q_handle

private

handle for general queues: parse, resolve, log.

hh

UT_hash_handle conn_s::hh

private

LRU cache handle. Only used for TCP connections.

in_read_queue

uint8_t conn_s::in_read_queue

Flag indicating if connection object is in read queue.

in_release_queue

uint8_t conn_s::in_release_queue

Flag indicating if connection object is in release queue. Only applies to TCP connections.

in_write_queue

uint8_t conn_s::in_write_queue

Flag indicating if connection object is in write queue.

ip_version

uint8_t conn_s::ip_version

Flag indicating if this conn is: 0=IPv4, 1=IPv6.

lc

uint8_t conn_s::lc

Flag indicating if 0=listener, or 1=connection(only applies to TCP).

proto

uint8_t conn_s::proto

Flag indicating protocol: 0=UDP, 1=TCP.

read_q_handle

struct conn_s* conn_s::read_q_handle

private

handle for read queue.

waiting_for_read

uint8_t conn_s::waiting_for_read

Flag indicating if connection object is waiting fore socket to become readable.

waiting_for_write

uint8_t conn_s::waiting_for_write

Flag indicating if connection object is waiting fore socket to become writable.

write_q_handle

struct conn_s* conn_s::write_q_handle

private

handle for write queue.
