typedef struct fr_schedule_s fr_schedule_t

Definition at line 1 of file schedule.h.

fr_schedule_thread_detach_t

typedef void(* fr_schedule_thread_detach_t) (void *uctx)

Explicitly free resources allocated by fr_schedule_thread_instantiate_t.

Parameters

[in]

uctx

User data passed to callback.

Definition at line 61 of file schedule.h.

fr_schedule_thread_instantiate_t

typedef int(* fr_schedule_thread_instantiate_t) (TALLOC_CTX *ctx, fr_event_list_t *el, void *uctx)

Setup a new thread.

Parameters

[in]	ctx	to allocate any thread specific memory in.
[in]	el	Event list used by the thread.
[in]	uctx	User data passed to callback.

Returns

• 0 on success.
• -1 on failure.

Function Documentation

fr_schedule_create()

fr_schedule_t* fr_schedule_create	(	TALLOC_CTX *	ctx,
		fr_event_list_t *	el,
		fr_log_t *	logger,
		fr_log_lvl_t	lvl,
		fr_schedule_thread_instantiate_t	worker_thread_instantiate,
		fr_schedule_thread_detach_t	worker_thread_detach,
		fr_schedule_config_t *	config
	)

Create a scheduler and spawn the child threads.

Parameters

[in]	ctx	talloc context.
[in]	el	event list, only for single-threaded mode.
[in]	logger	destination for all logging messages.
[in]	lvl	log level.
[in]	worker_thread_instantiate	callback for new worker threads.
[in]	worker_thread_detach	callback to destroy resources allocated by worker_thread_instantiate.
[in]	config	configuration for the scheduler

Returns

• NULL on error
• fr_schedule_t new scheduler

Here is the caller graph for this function:

fr_schedule_destroy()

int fr_schedule_destroy

(

fr_schedule_t **

sc_to_free

)

Destroy a scheduler, and tell its child threads to exit.

Note

This may be called with no worker or network threads in the case of a instantiation error. This function should deal with that condition gracefully.

Parameters

[in]

sc_to_free

the scheduler

Returns

• <0 on error
• 0 on success

Here is the caller graph for this function:

fr_schedule_directory_add()

fr_network_t* fr_schedule_directory_add	(	fr_schedule_t *	sc,
		fr_listen_t *	li
	)

Add a directory NOTE_EXTEND to a scheduler.

Parameters

[in]	sc	the scheduler
[in]	li	the ctx and callbacks for the transport.

Returns

• NULL on error
• the fr_network_t that the socket was added to.

Here is the caller graph for this function:

fr_schedule_listen_add()

fr_network_t* fr_schedule_listen_add	(	fr_schedule_t *	sc,
		fr_listen_t *	li
	)

Add a fr_listen_t to a scheduler.

Parameters

[in]	sc	the scheduler
[in]	li	the ctx and callbacks for the transport.

Returns

• NULL on error
• the fr_network_t that the socket was added to.

Here is the caller graph for this function:

fr_schedule_pthread_create()

int fr_schedule_pthread_create	(	pthread_t *	thread,
		void *(*)(void *)	func,
		void *	arg
	)

Creates a new thread using our standard set of options.

New threads are:

• Joinable, i.e. you can call pthread_join on them to confirm they've exited
• Immune to catchable signals.

Parameters

[out]	thread	handled that was created by pthread_create.
[in]	func	entry point for the thread.
[in]	arg	Argument to pass to func.

Returns

• 0 on success.
• -1 on failure.

fr_schedule_worker_id()

int fr_schedule_worker_id

(

void

)

Return the worker id for the current thread.

Returns

worker ID
