LLVM-libc should do what the standards say. For example, if the standards say that errno has to be set to a certain value to indicate error, then LLVM-libc should do that. Likewise, if standards say that the function in question should return an error value, then LLVM libc should do that.

I can probably give more specific answers if you can point out the particular function you are asking about.

Thanks,
