|
|
* KeWaitForSingleObject() is a tricky beast, because it can be used
|
|
* with several different object types: semaphores, timers, events,
|
|
* mutexes and threads. Semaphores don't appear very often, but the
|
|
* other object types are quite common. KeWaitForSingleObject() is
|
|
* what's normally used to acquire a mutex, and it can be used to
|
|
* wait for a thread termination.
|
|
*
|
|
* The Windows NDIS API is implemented in terms of Windows kernel
|
|
* primitives, and some of the object manipulation is duplicated in
|
|
* NDIS. For example, NDIS has timers and events, which are actually
|
|
* Windows kevents and ktimers. Now, you're supposed to only use the
|
|
* NDIS variants of these objects within the confines of the NDIS API,
|
|
* but there are some naughty developers out there who will use
|
|
* KeWaitForSingleObject() on NDIS timer and event objects, so we
|
|
* have to support that as well. Conseqently, our NDIS timer and event
|
|
* code has to be closely tied into our ntoskrnl timer and event code,
|
|
* just as it is in Windows.
|
|
*
|
|
* KeWaitForSingleObject() may do different things for different kinds
|
|
* of objects:
|
|
*
|
|
* - For events, we check if the event has been signalled. If the
|
|
* event is already in the signalled state, we just return immediately,
|
|
* otherwise we wait for it to be set to the signalled state by someone
|
|
* else calling KeSetEvent(). Events can be either synchronization or
|
|
* notification events.
|
|
*
|
|
* - For timers, if the timer has already fired and the timer is in
|
|
* the signalled state, we just return, otherwise we wait on the
|
|
* timer. Unlike an event, timers get signalled automatically when
|
|
* they expire rather than someone having to trip them manually.
|
|
* Timers initialized with KeInitializeTimer() are always notification
|
|
* events: KeInitializeTimerEx() lets you initialize a timer as
|
|
* either a notification or synchronization event.
|
|
*
|
|
* - For mutexes, we try to acquire the mutex and if we can't, we wait
|
|
* on the mutex until it's available and then grab it. When a mutex is
|
|
* released, it enters the signaled state, which wakes up one of the
|
|
* threads waiting to acquire it. Mutexes are always synchronization
|
|
* events.
|
|
*
|
|
* - For threads, the only thing we do is wait until the thread object
|
|
* enters a signalled state, which occurs when the thread terminates.
|
|
* Threads are always notification events.
|
|
*
|
|
* A notification event wakes up all threads waiting on an object. A
|
|
* synchronization event wakes up just one. Also, a synchronization event
|
|
* is auto-clearing, which means we automatically set the event back to
|
|
* the non-signalled state once the wakeup is done.
