C++ (Cpp) KeReadStateMutex Examples

Example #1

File: DrvFilter.c Project: 340211173/hf-2011

BOOL DrvFilter_IsLocked ()
{
  // verify that this module is initialized
  ASSERT (g_data.bInitialized) ;

  return 0==KeReadStateMutex(&g_data.mutex) ;
}

Example #2

File: semmutex-r0drv-nt.cpp Project: sobomax/virtualbox_64bit_edd

RTDECL(bool) RTSemMutexIsOwned(RTSEMMUTEX hMutexSem)
{
    /*
     * Validate.
     */
    RTSEMMUTEXINTERNAL *pThis = hMutexSem;
    AssertPtrReturn(pThis, false);
    AssertReturn(pThis->u32Magic == RTSEMMUTEX_MAGIC, false);

#ifdef RT_USE_FAST_MUTEX
    return pThis->Mutex && pThis->Mutex->Owner != NULL;
#else
    return KeReadStateMutex(&pThis->Mutex) == 1;
#endif
}
