Function rustix::mm::msync

pub unsafe fn msync(
    addr: *mut c_void, 
    len: usize, 
    flags: MsyncFlags
) -> Result<()>

msync(addr, len, flags)—Synchronizes a memory-mapping with its backing storage.

Safety

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