win32获取其它进程变量地址存放的信息

转自：http://www.cnblogs.com/hbb0b0/archive/2013/02/06/2907707.html

本文说明已知其它进程变量所在地址，如何读取此进程变量地址所保存的信息

Win32ReadMemTest的代码如下

#include "stdafx.h"
#include "windows.h"
int add(int a,int b);
typedef int (*func)(int,int);
int _tmain(int argc, _TCHAR* argv[])
{
    DWORD number=10000;
    DWORD *ptr=&number;
    func myfunc=NULL;
    myfunc=add;
    printf("%p: %d\n",ptr,*ptr);
    printf("func address:%p\n",myfunc);
    
    system("pause");
    return 0;
}
int add(int a,int b)
{
    return a+b;
}

运行Win32ReadMemTest
就会显示ptr的地址：0x002df914
