[Wine] Re: which is faster: WinApi or C Runtime?

[oiaohm]

If you are using pure C runtime you really need to consider if you should be using wine at all.  There are more and more ways to go native.

Currently C runtime ways are faster.  Mostly because optimisation has not been done on CreateFile() and the like instead they just wrap to fopen() and so on in glibc.   Wrapping has a price.

Sorry to say the exact other way to windows.   Its one place wine is a mirror image.   If you go the C runtime path you will take a hit on windows.  If you go the WinAPI path you take a hit on wine.
