A function call will take up CPU time, however it is very minimal as compared to what you are doing inside the function.

Bringing the function inline could actually make the operation slower under certain circumstances since it could change the optimization.

All this is mostly irrelevant since optimizations shouldn't be based on theory but on measurable results always keeping in mind the adage that 90% of your time is spent in 10% of your code. Also, the algorithm itself is more important than the implementation.

(By chance I was doing some optimizing this morning. So I modified the test a little and found that making an intermediate function call added about 8 CPU cycles per call on a Celeron 900. The result with the new algorithm was still 4x faster than the original algorithm.)

PS. You could use the keyword __forceinline if your test show that this will improve performance.
