Function Documentation

◆ __pthread_keys_exit()

void __pthread_keys_exit ( int  self_id)
[in]self_idthe result of pthread_self().

◆ pthread_getspecific()

void* pthread_getspecific ( pthread_key_t  key)
[in]keythe identifier for the requested tls
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 
[out]keythe created key is scribed to the given pointer
[in]destructorfunction pointer called when non NULL just befor the pthread exits
returns 0 on success, an errorcode otherwise

◆ pthread_key_delete()

int pthread_key_delete ( pthread_key_t  key)

does not call the destructor of the key

[in]keythe identifier of the key to be deleted
returns 0 on success, an errorcode otherwise

◆ pthread_setspecific()

int pthread_setspecific ( pthread_key_t  key,
const void *  value 
[in]keythe identifier for the tls
[in]valuepointer to the location of the tls
returns 0 on success, an errorcode otherwise
