Would this statement be true or false? I was told conflicting information in regards to mmap() and now I am unsure.
A program can memory map only a part of file rather than the whole file in Linux using mmap().

If you can't figure it out from the manual, why not build a simple program to try it? – Joseph Sible-Reinstate Monica Dec 16 '20 at 22:25

False -- a program can memory map part of a file, or the whole file.
Kind of a trick question, due to the confusing use of "only ... rather than", which is normally just used to emphasize things that are mutually exclusive.
This question perhaps belongs on https://english.stackexchange.com/ rather than here -- the question has little to do with mmap itself and more to do with the vagaries of English grammar.
