C++ (Cpp) OSWakeupThread Examples

Example #1

File: gx2_vsync.cpp Project: Tilka/wiiu-emu

void
VsyncAlarmHandler(OSAlarm *alarm, OSContext *context)
{
   gLastVsync = OSGetSystemTime();
   OSWakeupThread(gVsyncThreadQueue);
   auto callback = gEventCallbacks[GX2EventCallback::Vsync];

   if (callback.func) {
      callback.func(GX2EventCallback::Vsync, callback.data);
   }
}

Example #2

File: coreinit_alarm.cpp Project: Invertex/decaf-emu

/**
 * Internal alarm cancel.
 *
 * Reset the alarm state to cancelled.
 * Wakes up all threads waiting on the alarm.
 * Removes the alarm from any queue it is in.
 */

    if (alarm->state != OSAlarmState::Set) {
        return FALSE;
    }

        alarm->alarmQueue = nullptr;
    }

    OSWakeupThread(&alarm->threadQueue);
    return TRUE;
}

Example #3

File: coreinit_alarm.cpp Project: archshift/decaf-emu

static bool
OSTriggerAlarmNoLock(OSAlarm *alarm, OSContext *context)
{
   alarm->context = context;

   if (alarm->callback && alarm->state != OSAlarmState::Cancelled) {
