Use if(MAP_FAILED==bufp) . errno could have been modified by a previous
error. It won't be changed unless an error happens. So your mmap is
probably ok.

They don't, I think. Just you're using the wrong test. AT LEAST init
errno to 0 just before the function call, but that's ugly. Better
testing the CORRECT result first and check errno only when a failure
gets reported...
