Function Documentation

void kre_threads_complete

(

struct kre_thread *

t

)

Set things, and inform other task that actual task is completed.

Parameters:

t

Current kre thread structure.

struct kre_thread* kre_threads_fff

(

kre_threads

t

)

[read]

Find Firs Free kre_thread structure.

Parameters:

t

Set of threads to search.

Returns:

Thread which was found or NULL.

int kre_threads_find_by_pid	(	pid_t	p,
		kre_threads	t
	)

Find localization of kre_thread in kre_threads set by pid.

Parameters:

	p	Function search t set looking for pid p.
	t	Set of kre threads.

Returns:

id of kre_thread struct in set of kre threads or -1 if not found.

struct kre_thread* kre_threads_get_by_id	(	int	id,
		kre_threads	t
	)			[read]

Return kre thread by id.

Parameters:

	id	Identyficator returned for example by kre_threads_find_by_pid().
	t	Set of kre threads.

int kre_threads_init	(	struct kre_thread *	t,
		int(*)(void *)	f,
		void *	data
	)

Initialization of thread.

Parameters:

	t	Thread to initlize.
	f	Thread function.
	data	Pointer to external thread data. NOT WORK AT NOW.

Returns:

Error report or 0 if ok.

void kre_threads_register_one_thread

(

struct kre_thread *

t

)

Registration one thread.

This can be used to register main kREproxy server thread.

int kre_threads_should_work

(

struct kre_thread *

t

)

It can tell whether kthread should work or finish all jobs.

Parameters:

t

Current thread structure.

Returns:

0 - if should stop, 1 - if should work.

int kre_threads_start

(

struct kre_thread *

t

)

Starting the new thread.

Parameters:

t

Kreporxy thread to start.

Returns:

Error report.

int kre_threads_stop

(

struct kre_thread *

t

)

The main cause of exist this function is to kill main kreproxy server thread in clear way.

Parameters:

t

kre_thread structure with running task.

Returns:

Error output.
