c++ - C++：从注入的 DLL 读取内存的好方法是什么？

Question

我是这个专业领域的新手，所以我不完全确定......我知道你有两个功能： WriteProcessMemory 和 ReadProcessMemory ，但内部情况不同......我对指针也不够熟悉还没有自己做——但如果你能帮我评论一下，我想我会没事的:)。

那么，读取内存的最佳方法是什么？

顺便说一下，这是我的写记忆功能：

void WriteToMemory(DWORD addressToWrite, char* valueToWrite, int byteNum)
{
    //used to change our file access type, stores the old
    //access type and restores it after memory is written
    unsigned long OldProtection;
    //give that address read and write permissions and store the old permissions at oldProtection
    VirtualProtect((LPVOID)(addressToWrite), byteNum, PAGE_EXECUTE_READWRITE, &OldProtection);

    //write the memory into the program and overwrite previous value
    memcpy((LPVOID)addressToWrite, valueToWrite, byteNum);

    //reset the permissions of the address back to oldProtection after writting memory
    VirtualProtect((LPVOID)(addressToWrite), byteNum, OldProtection, NULL);
}

Answer 1

这是一种方法：

void ReadFromMemory(DWORD addressToRead, float value)
{
    value = *(float*)addressToRead;
}

还有其他建议吗？
