本文介绍了一种在Windows系统中遍历应用程序内存区域的方法。通过使用GetSystemInfo和VirtualQuery函数获取应用程序的最小地址和最大地址，并遍历这些区域来展示每个内存区域的基本信息。

    SYSTEM_INFO sysInfo = {0};

    GetSystemInfo(&sysInfo);

    DWORD dwMinAddr = (DWORD)sysInfo.lpMinimumApplicationAddress;
    DWORD dwMaxAddr = (DWORD)sysInfo.lpMaximumApplicationAddress;

    MEMORY_BASIC_INFORMATION memBase;
    int i = 0;

    for (dwMinAddr; dwMinAddr < dwMaxAddr;)
    {
        if (VirtualQuery((LPVOID)dwMinAddr, &memBase, sizeof(memBase)) == sizeof(memBase))
        {
            wprintf(_T("%d %x %x %d\r\n"),i ++,memBase.BaseAddress, memBase.RegionSize,memBase.AllocationProtect);
        }
        dwMinAddr += memBase.RegionSize;
    }

typedef struct _MEMORY_BASIC_INFORMATION 
{ 
    PVOID BaseAddress; 
    PVOID AllocationBase; 
    DWORD AllocationProtect; 
    DWORD RegionSize; 
    DWORD State; 
    DWORD Protect; 
    DWORD Type; 
} MEMORY_BASIC_INFORMATION;
