Check Leak using VmData

[ok97465]

I want to Check Memory Leak.
I checked VmData of /proc/pid/status.
I deleted Heap Region but VmData was not changed.

Help me.

Below is my testCode.

#include <stdio.h>
#include <unistd.h>

enum MATRIX_TYPE {
	MAT_TYPE_EMPTY=0, MAT_TYPE_REAL, MAT_TYPE_COMPLEX
};

template<class Type = float> class C2dMatrixIL {
protected:
	Type *pr;

public:
	C2dMatrixIL()
	{
		pr = 0;
	}

	~C2dMatrixIL()
	{
		C2dMatrixIL<Type>::Clear();
	}

	void SetSize(MATRIX_TYPE mat_type, int nrow, int ncol)
	{
		pr = new Type[nrow*ncol*MAT_TYPE_COMPLEX];
	}

	void Clear()
	{
		delete [] pr;
		pr = 0;
	}
};

int main() {
	sleep(5);
	while(1)
	{
		C2dMatrixIL<float> kk;
		kk.SetSize(MAT_TYPE_COMPLEX,1000,1000);
		printf("alloc state\n");
		sleep(10);

		kk.Clear();
		printf("Clear state\n");
		sleep(10);
	}
	return 0;
}

use valgrind

valgrind is a good tool to check memleak~
