PTHREAD_KEY_DELETE(3)     OpenBSD Programmer's Manual    PTHREAD_KEY_DELETE(3)

     pthread_key_delete - delete a thread-specific data key

     #include <pthread.h>

     pthread_key_delete(pthread_key_t key);

     The pthread_key_delete() function deletes a thread-specific data key pre-
     viously returned by pthread_key_create().  The thread-specific data val-
     ues associated with key need not be NULL at the time that
     pthread_key_delete() is called. It is the responsibility of the applica-
     tion to free any application storage or perform any cleanup actions for
     data structures related to the deleted key or associated thread-specific
     data in any threads; this cleanup can be done either before or after
     pthread_key_delete() is called. Any attempt to use key following the call
     to pthread_key_delete() results in undefined behavior.

     The pthread_key_delete() function is callable from within destructor
     functions. Destructor functions are not invoked by pthread_key_delete().
     Any destructor function that may have been associated with key will no
     longer be called upon thread exit.

     If successful, the pthread_key_delete() function will return zero. Other-
     wise an error number will be returned to indicate the error.

     pthread_key_delete() will fail if:

     [EINVAL]      The key value is invalid.

     pthread_getspecific(3),  pthread_key_create(3),  pthread_setspecific(3)

     pthread_key_delete() conforms to ISO/IEC 9945-1 ANSI/IEEE (``POSIX'') Std
     1003.1 Second Edition 1996-07-12.
