Virtual Memory in Qt 4.2.2

hi all,
i want to know tht is there any class or any feature of Qt 4.2.2 to handle virtual memory explicity. or any info regarding Virtual memory in Qt 4.2.2
i couldn't find any info on this topic.
thanks to all..

What do you want to do with VM? This is something the system handles and is transparent to applications, isn't it?

yes. you are right. thanks :-)
can anyone enlighten me that can we know that which API of Qt is using which system call. i actually want to know the difference in behaviour of Qt on window and linux and what leads to the difference.

What difference? C++ has built-in operators that handle memory allocation and deallocation.
