Deletes a thread-specific data key.
Threads Library (libpthreads.a)
#include <pthread.h>
int pthread_key_delete (pthread_key_t key);
The pthread_key_delete subroutine deletes the thread-specific data key key, previously created with the pthread_key_create subroutine. The application must ensure that no thread-specific data is associated with the key. No destructor routine is called.
Note: The pthread.h header file must be the first included file of each source file using the threads library. Otherwise, the -D_THREAD_SAFE compilation flag should be used, or the cc_r compiler used. In this case, the flag is automatically set.
| key | Specifies the key to delete. |
If successful, the pthread_key_delete function returns zero. Otherwise, an error number is returned to indicate the error.
The pthread_key_delete function will fail if:
| EINVAL | The key value is invalid. |
The pthread_key_delete function will not return an error code of EINTR.
This subroutine is part of the Base Operating System (BOS) Runtime.
The pthread_key_create subroutine, pthread.h file.
