Clearing Heap Memory

[Suresh_S]

Hi all....
Can i clear the heap memory before starting my app by using this line of code?
"Runtime.getRuntime().freeMemory()" //TO CLEAR HEAP MEMORY.
"Runtime.getRuntime().totalMemory()" //TO GET TOTAL HEAP MEMORY.
if yes where should i need to add this line of code?
Thank You.

I'm not certain what API that is thus can not be sure of the functionality, anyway, I suppose the freeMemory propably just returns the amount of free memory without doing any freeing really.

Thanks symbianyucca.
then how can i clear the heap memory before starting my application?

Generally you can not, system will take care of shutting down application that are not on foreground, once the RAM memory goes low. Thus you should mainly concentrate on managing the memory you are using, and clearing it once it is not needed anymore.

Hi wizard...
I have added this in .cpp file and
TInt WatchMem(TAny *)
{
TBuf<20> buf;
TInt size;
TInt count=User::AllocSize(size);
_LIT(KFormat,"%d/%d");
buf.Format(KFormat,size,count);
User::InfoPrint(buf);
return 1;
}

And This Line
CPeriodic::NewL(EPriorityStandard)->Start(1000000,1000000,TCallBack(WatchMem));

but i'm getting this error.
please help me.
function call '[TCallBack].TCallBack(int (CGlobalCapturer::*)(void *))' does not match

Suresh_S... is this related to your original post?
