Typedef Documentation

typedef struct __pthread_tls_key* pthread_key_t

A thread-specific key.

Definition at line 39 of file pthread_tls.h.

void __pthread_keys_exit ( int self_id )

Destroys all thread-specific keys for pthread self_id.

Parameters

[in] self_id the result of pthread_self().

void * pthread_getspecific ( pthread_key_t key )

Returns the requested tls.

Parameters

[in] key the identifier for the requested tls

int pthread_key_create	(	pthread_key_t *	key,
		void(*	destructor )(void *) )

Creates a new key to be used to identify a specific tls.

Parameters

[out]	key	the created key is scribed to the given pointer
[in]	destructor	function pointer called when non NULL just before the pthread exits

int pthread_key_delete ( pthread_key_t key )

Deletes a pthread_key_t that was previously created with pthread_key_create.

does not call the destructor of the key

Parameters

[in] key the identifier of the key to be deleted

int pthread_setspecific	(	pthread_key_t	key,
		const void *	value )

Set and binds a specific tls to a key.

Parameters

[in]	key	the identifier for the tls
[in]	value	pointer to the location of the tls
