NAMEpthread_key_delete — delete a thread-specific data key
LIBRARYPOSIX Threads Library (libpthread, -lpthread)
SYNOPSIS#include < pthread.h>
pthread_key_delete( pthread_key_t key);
DESCRIPTIONThe 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 VALUESIf successful, the pthread_key_delete() function will return zero. Otherwise an error number will be returned to indicate the error.
ERRORSThe pthread_key_delete() function will fail if:
- [ EINVAL]
- The key value is invalid.
STANDARDSThe pthread_key_delete() function conforms to ISO/IEC 9945-1:1996 (“POSIX.1”).
