discipline is associated with the **tty**. No other call into the line discipline for this tty will occur until it completes successfully. It should initialize any state needed by the ldisc, and set **tty->receive_room** to the maximum amount of data the line discipline is willing to accept from the driver with a single call to **receive_buf**. Returning an error will prevent the ldisc from being attached. Optional. Can sleep. This function is called when the line discipline is being shutdown, either because the **tty** is being closed or because the **tty** is being changed to use a new line discipline. At the point of execution no further users will enter the ldisc code for this tty. Optional. Can sleep. This function instructs the line discipline to clear its buffers of any input characters it may have queued to be delivered to the user mode process. It may be called at any point between open and close. Optional. This function is called when the user requests to read from the **tty**. The line discipline will return whatever characters it has buffered up for the user. If this function is not defined, the user will receive an ``EIO`` error. Multiple read calls may occur in parallel and the ldisc must deal with serialization issues. Optional: ``EIO`` unless provided. Can sleep. This function is called when the user requests to write to the **tty**. The line discipline will deliver the characters to the low-level tty device for transmission, optionally performing some processing on the characters first. If this function is not defined, the user will receive an ``EIO`` error. Optional: ``EIO`` unless provided. Can sleep. This function is called when the user requests an ioctl which is not handled by the tty layer or the low-level tty driver. It is intended for ioctls which affect line discpline operation. Note that the search order for ioctls is (1) tty layer, (2) tty low-level driver, (3) line discpline. So a low-level driver can "grab" an ioctl request before the line discpline has a chance to see it. Optional. Process ioctl calls from 32-bit process on 64-bit system. Note that only ioctls that are neither "pointer to compatible structure" nor tty-generic. Something private that takes an integer or a pointer to wordsize-sensitive structure belongs here, but most of ldiscs will happily leave it ``NULL``. Optional. This function notifies the line discpline that a change has been made to the termios structure. Optional. This function is called when a user attempts to select/poll on a **tty** device. It is solely the responsibility of the line discipline to handle poll requests. Optional. Called on a hangup. Tells the discipline that it should cease I/O to the tty driver. The driver should seek to perform this action quickly but should wait until any pending driver I/O is completed. No further calls into the ldisc code will occur. Optional. Can sleep. This function is called by the low-level tty driver to send characters received by the hardware to the line discpline for processing. **cp** is a pointer to the buffer of input character received by the device. **fp** is a pointer to an array of flag bytes which indicate whether a character was received with a parity error, etc. **fp** may be ``NULL`` to indicate all data received is ``TTY_NORMAL``.
