Implementations§

Source§

impl LINUX_TERMIOS_IFLAG

Source

pub const IGNBRK: c_uint = 1u32

Ignore BREAK condition on input.

Source

pub const BRKINT: c_uint = 2u32

Signal interrupt on BREAK. If IGNBRK is set, a BREAK is ignored.

If it is not set but BRKINT is set, then a BREAK causes the input and output queues to be flushed, and if the terminal is the controlling terminal of a foreground process group, it will cause a SIGINT to be sent to this foreground process group.

When neither IGNBRK nor BRKINT are set, a BREAK reads as a null byte (‘\0’), except when PARMRK is set, in which case it reads as the sequence \377 \0 \0.

Source

pub const IGNPAR: c_uint = 4u32

Ignore framing errors and parity errors.

Source

pub const PARMRK: c_uint = 10u32

Mark parity and framing errors.

If this bit is set, input bytes with parity or framing errors are marked when passed to the program.

This bit is meaningful only when INPCK is set and IGNPAR is not set.

The way erroneous bytes are marked is with two preceding bytes, \377 and \0.

Thus, the program actually reads three bytes for one erroneous byte received from the terminal.

If a valid byte has the value \377, and ISTRIP is not set, the program might confuse it with the prefix that marks a parity error.

Therefore, a valid byte \377 is passed to the program as two bytes, \377 \377, in this case.

If neither IGNPAR nor PARMRK is set, read a character with a parity error or framing error as \0.

Source

pub const INPCK: c_uint = 20u32

Enable input parity checking.

Source

pub const ISTRIP: c_uint = 40u32

Strip off eighth bit.

Source

pub const INLCR: c_uint = 100u32

Translate NL to CR on input.

Source

pub const IGNCR: c_uint = 200u32

Ignore CR (carriage return) on input.

Source

pub const ICRNL: c_uint = 400u32

Translate CR to NL (carriage return to newline) on input (unless IGNCR is set).

Source

pub const IUCLC: c_uint = 1_000u32

Map uppercase characters to lowercase on input (not in POSIX).

Source

pub const IXON: c_uint = 2_000u32

Enable XON/XOFF flow control on output.

Source

pub const IXANY: c_uint = 4_000u32

(XSI) Typing any character will restart stopped output.

(The default is to allow just the START character to restart output.)

Source

pub const IXOFF: c_uint = 10_000u32

Enable XON/XOFF flow control on input.

Source

pub const IMAXBEL: c_uint = 20_000u32

Ring bell when input queue is full (not in POSIX).

Linux does not implement this bit, and acts as if it is always set.

Source

pub const IUTF8: c_uint = 40_000u32

Input is UTF8. (not in POSIX)

This allows character-erase to be correctly performed in cooked mode.

(since Linux 2.6.4)
