Function	Description
GetCurrentProcessorNumber	Obtains the number of the processor on which the current thread is running during the call to this function.
CeGetIdleTimeEx	Obtains the idle time for the specified processor.
CeGetProcessAffinity	Obtains the process affinity for the specified process.
CeGetThreadAffinity	Obtains the thread affinity of the specified thread.
CeGetTotalProcessors	Obtains the total number of processors in the system.
CePowerOffProcessor	Turns off the specified processor.
CePowerOnProcessor	Turns on the specified processor.
CeSetProcessAffinity	Sets a processor affinity for the specified process.
CeSetThreadAffinity	Sets a processor affinity for the specified thread.
NKAcquireOalSpinLock	Acquires an OEM adaptation layer (OAL) spin lock to protect shared resources.
NKReleaseOalSpinLock	Releases an OAL spin lock that protects shared resources.
NKSendInterProcessorInterrupt	Sends a platform-specific interprocessor interrupt (IPI) to the specified processor.
OEMIdleEx	Places the CPUs in the idle state when there are no threads ready to run.
OEMIpiHandler	Handles platform-specific IPIs.
OEMMpCpuPowerFunc	Changes the power state of a specific CPU in a multiprocessor platform.
