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 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. ERRORS
pthread_key_delete() will fail if: [EINVAL] The key value is invalid. SEE ALSO
pthread_getspecific(3), pthread_key_create(3), pthread_setspecific(3) STANDARDS
pthread_key_delete() conforms to ISO/IEC 9945-1:1996 (``POSIX.1''). BSD
