Each process on 32-bit Microsoft Windows has its own virtual address space that enables addressing up to 4 gigabytes of memory. Each process on 64-bit Windows has a virtual address space of 8 terabytes. All threads of a process can access its virtual address space. However, threads cannot access memory that belongs to another process, which protects a process from being corrupted by another process.

For information on the virtual address space and the memory management functions, see the following topics.

• Virtual Address Space

• Memory Performance Information
• Virtual Memory Functions
• Heap Functions
• File Mapping
• Large Memory Support
• Global and Local Functions
