LARGE_INTEGER? Trying to get a timer to work

[RyoxSinfar]

I have a program and it is imparative (see big word and glory in my importance <.< lol ) that I know how long some functions take to process. So I was given tested code to do this. This code included the use of LARGE_INTEGERs and my compiler didn't like them. What is required for me to use LARGE_INTEGER? also is there anything required to use the function QueryPerformanceCounter()? I am not entirely sure how these this function does what it does but for now it is okay to just get it working.

Thank you for any time spent.
