呼叫ZwAllocateVirtualMemory所配置的記憶體,必須藉由呼叫 ZwFreeVirtualMemory來釋放。 如需記憶體管理的詳細資訊,請參閱Windows 驅動程式的記憶體管理。 注意 如果在使用者模式中呼叫ZwAllocateVirtualMemory函式,您應該使用名稱 “NtAllocateVirtualMemory”,而不是 “ZwAllocateVirtualMemory”。
通过调用ZwAllocateVirtualMemory分配的内存必须通过调用ZwFreeVirtualMemory来释放。 有关内存管理的详细信息,请参阅适用于 Windows 驱动程序内存管理。 备注 如果在用户模式下调用ZwAllocateVirtualMemory函数,则应使用名称“NtAllocateVirtualMemory”而不是“ZwAllocateVirtualMemory”。
Windows 10x64, has 76 Gb free real memory, and have very small (1Gb) virtual memory. Program compiled as x64 application, and at the attempt to allocate 3Gb memory matrix ends with message severe (41): insufficient virtual memory. May be (but it strange) it needs namely VIRTUAL, not ...
In my first Pushing the Limits of Windows post, I discussed physical memory limits, including the limits imposed by licensing, implementation, and driver compatibility. Here’s the index of the entire Pushing the Limits series. While they can stand on their own, they assume that you r...

Figure 1. The Windows API provides different levels of memory management for versatility in application programming. In all, six sets of memory management functions exist in Windows, as shown in Figure 1, all of which were designed to be used independently of one another. So, which set of fu...
Clint Huffman, in Windows Performance Analysis Field Guide, 2015 Virtual memory and paging files Paging files are often referred to as “virtual memory” because they allow the system to back more virtual memory allocations than what is normally possible with physical memory alone. Figure 4.16 is ...
