- * DOCPUBLIC
- * This function creates a thread-specific data key visible
- * to all threads. All existing and new threads have a value
- * NULL for key until set using pthread_setspecific. When any
- * thread with a non-NULL value for key terminates, 'destructor'

- * DESCRIPTION
- * This function creates a thread-specific data key visible
- * to all threads. All existing and new threads have a value
- * NULL for key until set using pthread_setspecific. When any
- * thread with a non-NULL value for key terminates, 'destructor'
- * is called with key's current value for that thread.
- *
- * RESULTS
- * 0 successfully created semaphore,
- * EAGAIN insufficient resources or PTHREAD_KEYS_MAX
- * exceeded,
- * ENOMEM insufficient memory to create the key,
