pub fn open<P: Arg>(path: P, flags: OFlags, mode: Mode) -> Result<OwnedFd>Available on crate feature
fs only.Expand description
open(path, oflags, mode)—Opens a file.
POSIX guarantees that open will use the lowest unused file descriptor,
however it is not safe in general to rely on this, as file descriptors may
be unexpectedly allocated on other threads or in libraries.
The Mode argument is only significant when creating a file.
