Function open

pub fn open<P: Arg>(name: P, flags: OFlags, mode: Mode) -> Result<OwnedFd>

shm_open(name, oflags, mode)—Opens a shared memory object.

For portability, name should begin with a slash, contain no other slashes, and be no longer than an implementation-defined limit (255 on Linux).

Exactly one of shm::OFlags::RDONLY and shm::OFlags::RDWR should be passed. The file descriptor will be opened with FD_CLOEXEC set.
