std::byte *ReadBytes(PVOID address, SIZE_T length)
{
std::byte *buffer = new std::byte[length];
std::cout << "length" << sizeof(buffer) << std::endl;
ReadProcessMemory(this->processHandle, address, buffer, length, NULL);
return buffer;
};
I'm trying to read memory regions of a process into std::byte array, but with code above, I can't get the length of buffer outside, so I want to change the type of buffer to std::vector<std::byte>
or use some other methods. How can I do this?
Since C++11, std::vector::data
will provide a pointer to the backing array. If you're using older tools without support for C++ 11, &buffer[0]
probably works, I've never seen it not work, but is not guaranteed by the Standard.
Looking at the code again, if you've got std::byte
, C++11 support is not an issue.
So...
std::vector<std::byte> ReadBytes(PVOID address, SIZE_T length) { std::vector<std::byte> buffer(length); std::cout << "length" << buffer.size() << std::endl; ReadProcessMemory(this->processHandle, address, buffer.data(), length, NULL); return buffer; };
