The context key identifies the thread-specific data to be obtained. Obtain this key by calling the pthread_key_create(3) routine.
This routine obtains the thread-specific data associated with the specified key for the current thread. This routine returns the value currently bound to the specified key on behalf of the calling thread.
This routine may be called from a thread-specific data destructor function.
No errors are returned. This routine returns the thread-specific data value associated with the specified key argument. If no thread-specific data value is associated with key, or if key is not defined, then this routine returns a NULL value.
Functions: pthread_key_create(3), pthread_setspecific(3)
