|PTHREAD_KEY_DELETE(3)||Library Functions Manual||PTHREAD_KEY_DELETE(3)|
pthread_key_delete() function deletes a thread-specific data key previously returned by
pthread_key_create(). The thread-specific data values associated with key need not be NULL at the time that
pthread_key_delete() is called. It is the responsibility of the application 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.
pthread_key_delete() function is
callable from within destructor functions. Destructor functions are not
pthread_key_delete(). Any destructor
function that may have been associated with key will
no longer be called upon thread exit.
pthread_key_delete() function will return zero. Otherwise an error number will be returned to indicate the error.
pthread_key_delete() will fail if:
pthread_key_delete() conforms to ISO/IEC 9945-1:1996 (“POSIX.1”).
