-ptw32_tkAssocCreate (ptw32_thread_t * sp, pthread_key_t key)
- /*
- * -------------------------------------------------------------------
- * This routine creates an association that
- * is unique for the given (thread,key) combination.The association
- * is referenced by both the thread and the key.
- * This association allows us to determine what keys the
- * current thread references and what threads a given key
- * references.
- * See the detailed description
- * at the beginning of this file for further details.
- *
- * Notes:
- * 1) New associations are pushed to the beginning of the
- * chain so that the internal ptw32_selfThreadKey association
- * is always last, thus allowing selfThreadExit to
- * be implicitly called last by pthread_exit.
- * 2)
- *
- * Parameters:
- * thread
- * current running thread.
- * key
- * key on which to create an association.
- * Returns:
- * 0 - if successful,
- * ENOMEM - not enough memory to create assoc or other object
- * EINVAL - an internal error occurred
- * ENOSYS - an internal error occurred
- * -------------------------------------------------------------------
