Function Documentation

worker_create()

struct worker * worker_create	(	struct daemon *	daemon,
		int	id,
		int *	ports,
		int	n )

Create the worker structure. Bare bones version, zeroed struct, with backpointers only. Use worker_init on it later.

Parameters

daemon	the daemon that this worker thread is part of.
id	the thread number from 0.. numthreads-1.
ports	the ports it is allowed to use, array.
n	the number of ports.

Returns

: the new worker or NULL on alloc failure.

worker_delete()

void worker_delete

(

struct worker *

worker

)

Delete worker.

worker_init()

int worker_init	(	struct worker *	worker,
		struct config_file *	cfg,
		struct listen_port *	ports,
		int	do_sigs )

Initialize worker. Allocates event base, listens to ports

Parameters

worker	worker to initialize, created with worker_create.
cfg	configuration settings.
ports	list of shared query ports.
do_sigs	if true, worker installs signal handlers.

Returns

: false on error.

worker_send_cmd()

void worker_send_cmd	(	struct worker *	worker,
		enum worker_commands	cmd )

Send a command to a worker. Uses blocking writes.

Parameters

worker	worker to send command to.
cmd	command to send.

worker_stats_clear()

void worker_stats_clear

(

struct worker *

worker

)

Init worker stats - includes server_stats_init, outside network and mesh.

Parameters

worker

the worker to init

worker_work()

void worker_work

(

struct worker *

worker

)

Make worker work.
