PTHREAD_KEY_DELETE(3) OpenBSD Programmer's Manual PTHREAD_KEY_DELETE(3)NAMEpthread_key_delete - delete a thread-specific data key
SYNOPSIS
#include <pthread.h>
int
pthread_key_delete(pthread_key_t key);
DESCRIPTION
The 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.
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.
RETURN VALUES
If successful, the pthread_key_delete() function will return zero.
Otherwise an error number will be returned to indicate the error.
ERRORSpthread_key_delete() will fail if:
[EINVAL] The key value is invalid.
SEE ALSOpthread_getspecific(3), pthread_key_create(3), pthread_setspecific(3)STANDARDSpthread_key_delete() conforms to ISO/IEC 9945-1:1996 (``POSIX'').
