页面的内存 页内存 页面内存 是什么?
VirtualAllocEx
VirtualAllocEx 函数的作用是在指定进程的虚拟空间保留或提交内存区域，除非指定MEM_RESET参数，否则将该内存区域置0。
函数原形：
LPVOID VirtualAllocEx(
HANDLE hProcess,
LPVOID lpAddress,
SIZE_T dwSize,
DWORD flAllocationType,
DWORD flProtect
);
hProcess：
申请内存所在的进程句柄。
lpAddress：
保留页面的内存地址；一般用NULL自动分配 。
dwSize：
欲分配的内存大小，字节单位；注意实际分 配的内存大小是页内存大小的整数倍
flAllocationType 可取下列值：... ...
页面内存是什么概念啊???????
在学远程注入...

翻译是很到位的
这里的页面内存 LZ你可以理解成自己程序的内存 你可以指定从那个地址分配空间
不过 一般都是WINDOWS 帮我们分配

虚拟内存管理中，是按页来作为元单位的，一般是4K大小。系统通过LRU算法，对近期未使用的页进行置换，当发生缺页中断的时候

你那些糟糕的翻译哪里看来的？
hProcess
The handle to a process. The function allocates memory within the virtual address space of this process.
The handle must have the PROCESS_VM_OPERATION access right. For more information, see Process Security and Access Rights.
lpAddress
The pointer that specifies a desired starting address for the region of pages that you want to allocate.
If you are reserving memory, the function rounds this address down to the nearest multiple of the allocation granularity.
If you are committing memory that is already reserved, the function rounds this address down to the nearest page boundary. To determine the size of a page and the allocation granularity on the host computer, use the GetSystemInfo function.
If lpAddress is NULL, the function determines where to allocate the region.
dwSize
The size of the region of memory to allocate, in bytes.
If lpAddress is NULL, the function rounds dwSize up to the next page boundary.
If lpAddress is not NULL, the function allocates all pages that contain one or more bytes in the range from lpAddress to lpAddress+dwSize. This means, for example, that a 2-byte range that straddles a page boundary causes the function to allocate both pages.
