new invokes VirtualAlloc

[George2]

Hello everyone,


On Windows, when we allocate large amount of memory, new will call
VirtualAlloc directly, other than call HeapAlloc then through
HeapAlloc call VirtualAlloc indirectly?

Anyone to clarify this?


thanks in advance,
George

It's hard to find a question in your post but I think what you are
asking about is implementation specific behavior. In other words,
compiler/library specific. Why do you need to know? Performance?
Failure?
