A program can delete the handles that it owns. Deleting a handle does not invalidate its ancestors and descendants (in contrast to revoking a handle, which actually invalidates the descendants of the handle). In other words, the ancestors and descendants of a deleted handle can still be used to provide access to the resource that they identify. Also, deleting a handle does not disrupt the handle inheritance tree associated with the resource identified by the particular handle. The place of a deleted handle is occupied by its ancestor. In other words, the ancestor of a deleted handle becomes the direct ancestor of the descendants of the deleted handle.
Handles are deleted by using the KnHandleClose() function, which is declared in the coresrv/handle/handle_api.h header file.
handle_api.h (fragment)
/**
* Deletes the handle.
* If successful, the function returns rcOk, otherwise it returns an error code.
*/
Retcode KnHandleClose(Handle handle);
