示例1: calloc

	PerformanceCounter *perfCounter;

	DWORD cpuIndex, nodeId, coreId;
	PROCESSORMASK cpuMask;
	unsigned int perfCounterSlot;

	uint64_t misses;

	// This pointers will refer an array containing previous performance counter values
	uint64_t *prevPerfCounters;

	try {

		p->setNode(p->ALL_NODES);
		p->setCore(p->ALL_CORES);

		 we need to retrieve the time stamp counter */

		prevPerfCounters = (uint64_t *) calloc(
				p->getProcessorCores() * p->getProcessorNodes(),
				sizeof(uint64_t));

		//use the findAvailable slot method to find an available method to be used
