Question

I need to translate this code into c++ (microsoft c++ ATL/MFC)project.

            var ticks = System.DateTime.Now.Ticks;
            byte[] c = BitConverter.GetBytes(ticks);
            byte[] buffer = new byte[c.Length];
            for (int i = 0; i < buffer.Length; i++)
            buffer[i] = (byte)c[i];

1. What is corresponding call in c++ for System.dateTime.Now.Ticks?

2. What is corresponding Bitconverter in c++.

Note: Boost is not an option in this project.

Answer 1

GetTickCount() may work as an equivalent:

It returns a value of 32 bits (DWORD), so the buffer would be of size = 4 bytes.
Regarding bitconverter, you don’t need it, since C++ can cast the pointer directly:

DWORD ticks = GetTickCount();
BYTE* buffer = (BYTE*)&ticks;
