What is the 64 bit version of GetTextExtent

Question

I'm porting our 32 bit windows app to 64 bit, and trying to clean up all the warnings. I have found calls in our code to CDC::GetTextExtent which take an int as a parameter.

I notice that GetTextExtent simply calls GetTextExtentPoint32. The 32 scares me, so i started looking for a 64 bit version of GetTextExtent but i can't find one.

Can anyone tell me is GetTextExtent totally safe in 64 bit? Or is there some other way we're supposed to get that information?

Thanks

According to the documentation, GetTextExtentPoint32 was added in 32-bit operating systems in order to provider more accurate results (I guess GetTextExtentPoint had a few limitations). All of the parameters are identical, so it doesn't have anything to do with 16-bit vs 32-bit vs 64-bit as far as I can tell. It would have made more sense to call it GetTextExtentPointEx or something, but what's done is done.
