Thread create(...) problem

Hello to all,

1. I'm trying for a few hours/days to solve this problem so every advice would be welcome, not to saying solution   

So this is how it goes:

TThreadFunction threadFunction = ThreadPrivateActions::aFunction((TAny *)this);
const TInt KMinHeapSize = 0x1000;
const TInt KMaxHeapSize = 0x1000000;
RThread().Create(name, threadFunction, KDefaultStackSize, KMinHeapSize, KMaxHeapSize, (void*) this);

Class 'ThreadPrivateActions' just contains a method with following "signature": static TInt aFunction(TAny *data) {...blah blah...}

I get the compiler error:
illegal implicit conversion from 'int' to 'int (*)(void *)'

which is true, obiovilusly, but I don't know how to solve this, what to do....


2. BTW, is it secure to put that range for heap and deafult stack size for stack?

Thanx!
