Function Documentation
◆ __pthread_keys_exit()
| 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().
◆ pthread_getspecific()
| void* pthread_getspecific | ( | pthread_key_t | key | ) |
Returns the requested tls.
- Parameters
-
[in] key the identifier for the requested tls
- Returns
- returns pointer to the storage on success, a 0 value otherwise
◆ pthread_key_create()
| int pthread_key_create | ( | pthread_key_t * | key, |
| void(*)(void *) | destructor | ||
| ) |
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
- Returns
- returns 0 on success, an errorcode otherwise
◆ pthread_key_delete()
| 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
- Returns
- returns 0 on success, an errorcode otherwise
◆ pthread_setspecific()
| 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
- Returns
- returns 0 on success, an errorcode otherwise
