55 When an open() call has succeeded, the device will be ready for use. The
56 significance of blocking or non-blocking mode is described in the
57 documentation for functions where there is a difference. It does not
58 affect the semantics of the open() call itself. A device opened in
59 blocking mode can later be put into non-blocking mode (and vice versa)
60 using the F_SETFL command of the fcntl system call. This is a standard
61 system call, documented in the Linux manual page for fcntl. Only one
62 user can open the CA Device in O_RDWR mode. All other attempts to open
63 the device in this mode will fail, and an error code will be returned.
