* Function: pthread_key_create
* Name: pthread_key_create
*
* Description:
* This function creates a thread-specific data key visible
* to all threads in the system. Although the same key value
* may be used by different threads, the values bound to
* the key by pthread_setspecific() are maintained on a
* per-thread basis and persist for the life of the calling
* This function creates a thread-specific data key visible to all threads
* in the system. Although the same key value may be used by different
* threads, the values bound to the key by pthread_setspecific() are
* maintained on a per-thread basis and persist for the life of the calling
* thread.
*
* Upon key creation, the value NULL will be associated with
* the new key in all active threads. Upon thread
* creation, the value NULL will be associated with all
* defined keys in the new thread.
* Upon key creation, the value NULL will be associated with the new key
* in all active threads. Upon thread creation, the value NULL will be
* associated with all defined keys in the new thread.
*
* Parameters:
* key = A pointer to the key to create.
* destructor = An optional destructor() function that may
* be associated with each key that is invoked when a
* thread exits. However, this argument is ignored in
* the current implementation.
* destructor = An optional destructor() function that may be associated

* argument is ignored in the current implementation.
*
* Return Value:
* If successful, the pthread_key_create() function will
* store the newly created key value at *key and return
* zero (OK). Otherwise, an error number will be
* returned to indicate the error:
