Description The bindprocessor kernel service binds a single kernel thread, or all kernel threads in a process, to a processor, forcing the bound threads to be scheduled to run on that processor only. It is important to understand that a process itself is not bound, but rather its kernel threads are bound. Once kernel threads are bound, they are always scheduled to run on the chosen processor, unless they are later unbound. When a new thread is created using the thread_create kernel service, it has the same bind properties as its creator.
Execution Environment The compare_and_swap kernel service can be called from either the process or interrupt environment. Return Values TRUE FALSE Indicates that the single word variable was equal to the old value, and has been set to the new value. Indicates that the single word variable was not equal to the old value, and that its current value has been returned in the location where the old value was stored.
