Abstract
Techniques are disclosed for providing thread specific protection levels in a multithreaded processing environment. An associated method includes generating a group of threads in a process, one of the group of threads opening a thread entity, and that one of the group of threads specifying one or more levels of access to the thread entity for the other threads. In one embodiment, when a first of the threads attempts to perform a specified operation on the thread entity, the method of this invention determines whether that first thread is the one of the group of threads that opened the thread entity. When the first thread is not that one of the group of threads, the first thread is allowed to perform the specified operation if and only if such operation is permitted by the specified one or more levels of access.
