make typedef a 64-bit unsigned

 make typedef a 64-bit unsigned

I am trying to make typedef a 64-bit unsigned and getting error. How do I typedef 64-bit

typedef unsigned long long QWORD; // 64-bit unsigned

error C141: syntax error near 'long'

Have a look at this link:

If you need a 64-bit integer, you will have to implement that logic yourself. Do you need full math support, or is it just for some kind of counter?
