从Linux到Windows的C ++

如何解决从Linux到Windows的C ++

我目前正在从Linux到Windows重建我的项目，我在重建功能上没有什么问题，我在Linux上经验丰富，我不知道如何重建您看到的评论

唯一的问题是

 mprotect(page,mprot_len,PROT_READ | PROT_WRITE | PROT_EXEC)

这是我的代码，我不知道替换它

class BytePatch
{
    void *addr{ 0 };
    size_t size;
    std::vector<unsigned char> patch_bytes;
    std::vector<unsigned char> original;
    bool patched{ false };

public:
    ~BytePatch()
    {
        Shutdown();
    }
    BytePatch(std::function<uintptr_t(const char *)> SigScanFunc,const char *pattern,size_t offset,std::vector<unsigned char> patch) : patch_bytes{ patch }
    {
        addr = (void *) SigScanFunc(pattern);
        if (!addr)
        {
            logging::Info("Signature not found");
            throw std::runtime_error("Signature not found");
        }
        addr = static_cast<void *>(static_cast<char *>(addr) + offset);
        size = patch.size();
        original.resize(size);
        memcpy(&original[0],addr,size);
    }
    BytePatch(uintptr_t addr,std::vector<unsigned char> patch) : addr{ reinterpret_cast<void *>(addr) },patch_bytes{ patch }
    {
        size = patch.size();
        original.resize(size);
        memcpy(&original[0],reinterpret_cast<void *>(addr),size);
    }
    BytePatch(void *addr,std::vector<unsigned char> patch) : addr{ addr },size);
    }

    void Patch()
    {
        if (!patched)
        {
            void *page          = (void *) ((uint64_t) addr & ~0xFFF);
            void *end_page      = (void *) (((uint64_t)(addr) + size) & ~0xFFF);
            uintptr_t mprot_len = (uint64_t) end_page - (uint64_t) page + 0xFFF;

            mprotect(page,PROT_READ | PROT_WRITE | PROT_EXEC); // this one 
            memcpy(addr,&patch_bytes[0],size);
            mprotect(page,PROT_EXEC); // this one 
            patched = true;
        }
    }
    void Shutdown()
    {
        if (patched)
        {
            void *page          = (void *) ((uint64_t) addr & ~0xFFF);
            void *end_page      = (void *) (((uint64_t)(addr) + size) & ~0xFFF);
            uintptr_t mprot_len = (uint64_t) end_page - (uint64_t) page + 0xFFF;

            mprotect(page,PROT_READ | PROT_WRITE | PROT_EXEC); // this one
            memcpy(addr,&original[0],PROT_EXEC); // this one
            patched = false;
        }
    }
};
