  • dup3(fd, new, flags)—Changes the file description of a file descriptor, with flags.
  • fcntl(fd, F_DUPFD_CLOEXEC)—Creates a new OwnedFd instance, with value at least min, that has O_CLOEXEC set and that shares the same underlying file description as fd.
  • fcntl(fd, F_GETFD)—Returns a file descriptor’s flags.
  • fcntl(fd, F_SETFD, flags)—Sets a file descriptor’s flags.
  • ioctl(fd, FIONBIO, &value)—Enables or disables non-blocking mode.
  • ioctl(fd, FIONREAD)—Returns the number of bytes ready to be read.
  • Returns a pair of booleans indicating whether the file descriptor is readable and/or writable, respectively.
