Expand description

posix_madvise(addr, len, advice)—Declares an expected access pattern for a memory-mapped file.

Safety

addr must be a valid pointer to memory that is appropriate to call posix_madvise on. Some forms of advice may mutate the memory or evoke a variety of side-effects on the mapping and/or the file.
