由于上个帖子不知为何莫名其妙被删。故此重发一遍。有违规请如实告知，代码为原创。

特征码格式： AA BB ?? DD ?? FF （与OD一致），若想其替代别的通配符，请自行修改。

请使用VS2017以上版本编译，最低要求C++ 17，为了方便。若你使用在vs2017以下版本，请自行将代码降级。

最下方有调用例子。

SearchPatternEx 最低要求32纳米CPU。

老师，我用vs2013有2处不知道咋改，老师帮忙看看，谢谢了，如下图：

auto masks = std::array<std::size_t, 32>{};
auto n = static_cast<std::size_t>(0);
auto pos = start;
for (auto i = static_cast<std::size_t>(0); i < count; ++i)
//for (auto[masks, i, n, pos] = std::make_tuple(std::array<std::size_t, 32>{}, static_cast<std::size_t>(0), static_cast<std::size_t>(0), start); i < count; ++i)

auto j = static_cast<std::size_t>(0);
for (auto store = _mm_loadu_si128(reinterpret_cast<const __m128i *>(chars.c_str() + i * 16)); pos <= end; _mm_prefetch(reinterpret_cast<const char*>(++pos + 64), _MM_HINT_NTA))
//for (auto[store, j] = std::make_tuple(_mm_loadu_si128(reinterpret_cast<const __m128i *>(chars.c_str() + i * 16)), static_cast<std::size_t>(0)); pos <= end; _mm_prefetch(reinterpret_cast<const char*>(++pos + 64), _MM_HINT_NTA))

编译应该能通过，结果对不对我不清楚

auto masks = std::array{};
auto n = static_cast(0);
auto pos = start;

谢谢老师，这个咋玩的没搞明白，不用输入进程id吗？如何查找某个进程特征码的内存地址呢？
