Function rustix::io::madvise[−][src]

pub unsafe fn madvise(
    addr: *mut c_void, 
    len: usize, 
    advice: Advice
) -> Result<()>
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.
