Function obnth::open_beneath[−][src]

pub fn open_beneath<P: AsPath>(
    dir_fd: RawFd, 
    path: P, 
    flags: c_int, 
    mode: mode_t, 
    lookup_flags: LookupFlags
) -> Result<File>

Open a file beneath the specified directory.

This is equivalent to libc::openat(dir_fd, path, flags, mode) except for the following differences:

  1. The resolved file is guaranteed to be within the directory referred to by dir_fd.
  2. The lookup_flags argument can further alter behavior during path resolution; see LookupFlags for more information.
  3. The file will be opened with O_CLOEXEC|O_NOCTTY, so its close-on-exec flag will be set and it cannot become the process's controlling terminal.
