WebUse pthread_key_create (3C) to allocate a key that is used to identify thread-specific data in a process. The key is global to all threads in the process. When the thread-specific data is created, all threads initially have the value NULL associated with the key. Call pthread_key_create () once for each key before using the key. Webpthread_key_t is a storage area where the system places the key identifier. To create a key, a thread uses pthread_key_create(). This returns the key identifier into the storage area of type pthread_key_t.
