OUT uint32 *pHostNumbersArray,
IN uint32 ArraySize,
OUT uint32 *pActualSize );
Arguments:
Handle the handle of the current session
pHostNumbersArray pointer to the array where the list of host numbers is placed
ArraySize - the size (in items of type uint32) of the buffer initially provided for the
array by the caller
