// Typedef for prototype of function to be used as main 
// function of a thread 

// Note: currently we use the same prototype for thread functions on all 
// platforms, in order to make user programs less platform-dependent.
// However, there is a distinction in returned value for the thread function
// on UNIX/Linux (void*) and WIndows (DWORD) systems. 
// Thus on Windows we have to encode returned void* as DWORD. It is OK for WIN32,
// but potentially problem on WIN64. 
// To avoid any problems with this, for better application portability it is recomended 
// that the thread function returns just integer (casted to void*). 
// This shall work on all platforms.
