I think this example will solved your problem.
Code:
#include<malloc.h>

int* fun();
int main()
{
  int *p2 = fun();
  free(p2);
  return 0;
 }

int* fun()
{
  int *p1 = (int *)malloc(10);
  return p1;
}

to check memory leak, you can use my program as
Code:
#include<malloc.h>
#include "findLeak.h"


int* fun();
int main()
{
  int *p2 = fun();
  free(p2);
  WriteMemLeak();
  return 0;
 }

int* fun()
{
  int *p1 = (int *)malloc(10);
  return p1;

}

that means you want to say that i need to free the memory in the function where i m receiving the value returned by temporary variable.

Can you tell me in different languages how to use this program?

suppose ive detected memory leaks on my OS as I run that program, what will I do next?
Is there any posible ways to prevent it or get rid of it?

You can make my program in binary also.

Beauty of this program is that only one interface you have to use, that is "WriteMemLeak()" only.
If any way other languages support to use C Interface, then you can use it.

I am not getting your question.

Is it true what i am understanding that "memory leak is in OS not in your program".
If it is true then your question is
"How to detect memory leak coming in OS by program posted by asadullah.ansari? "

Response me?
