private

Constructor & Destructor Documentation

ACE_TSS_Cleanup::ACE_TSS_Cleanup ( void  )

private

Ensure singleton.

private

Member Function Documentation

void ACE_TSS_Cleanup::dump ( void  )

private

bool ACE_TSS_Cleanup::find_tss_keys ( ACE_TSS_Keys *&  thread_keys ) const

private

Find the TSS keys (if any) for this thread.

Parameters

thread_keys

reference to pointer to be filled in by this function.

Returns

false if keys don't exist.

int ACE_TSS_Cleanup::free_key

(

ACE_thread_key_t

key

)

This key is no longer used Release key if use count == 0 fail if use_count != 0;

Parameters

key	the key to be released

int ACE_TSS_Cleanup::insert	(	ACE_thread_key_t	key,
		void(*)(void *)	destructor
	)

Register a newly-allocated key

Parameters

key	the key to be monitored
destructor	the function to call to delete objects stored via this key

int ACE_TSS_Cleanup::remove_key ( ACE_TSS_Info &  info )

private

remove key if it's unused (thread_count == 0)

Parameters

info	reference to the info for this key

int ACE_TSS_Cleanup::thread_detach_key

(

ACE_thread_key_t

key

)

This thread is no longer using this key call destructor if appropriate

void ACE_TSS_Cleanup::thread_exit

(

void

)

Cleanup the thread-specific objects. Does NOT exit the thread. For each used key perform the same actions as free_key.

void ACE_TSS_Cleanup::thread_release ( ACE_TSS_Info &  info, ACE_TSS_Info::Destructor &  destructor, void *&  tss_obj  )

private

Release a key used by this thread

Parameters

info	reference to the info for this key
destructor	out arg to receive destructor function ptr
tss_obj	out arg to receive pointer to deletable object

void ACE_TSS_Cleanup::thread_use_key

(

ACE_thread_key_t

key

)

Mark a key as being used by this thread.

ACE_TSS_Keys * ACE_TSS_Cleanup::tss_keys ( )

ACE_thread_key_t ACE_TSS_Cleanup::in_use_

private

Key for the thread-specific ACE_TSS_Keys Used by find_tss_keys() or tss_keys() to find the bit array that records whether each TSS key is in use by this thread.

ACE_TSS_TABLE ACE_TSS_Cleanup::table_

private

Table of <ACE_TSS_Info>'s.
