pthread_key_delete(3) BSD Library Functions Manual pthread_key_delete(3)
NAME
pthread_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 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.
RETURN VALUES
If successful, the pthread_key_delete() function will return zero. Oth-
erwise, an error number will be returned to indicate the error.
ERRORS
pthread_key_delete() will fail if:
[EINVAL] The key value is invalid.
