Implementations§

Source§

impl LINUX_TERMIOS_OFLAG

Source

pub const OPOST: c_uint = 1u32

Enable implementation-defined output processing.

Source

pub const OLCUC: c_uint = 2u32

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

Source

pub const ONLCR: c_uint = 4u32

(XSI) Map NL to CR-NL on output.

Source

pub const OCRNL: c_uint = 10u32

Map CR to NL on output.

Source

pub const ONOCR: c_uint = 20u32

Don’t output CR at column 0.

Source

pub const ONLRET: c_uint = 40u32

The NL character is assumed to do the carriage-return function; the kernel’s idea of the current column is set to 0 after both NL and CR.

Source

pub const OFILL: c_uint = 100u32

Send fill characters for a delay, rather than using a timed delay.

Source

pub const OFDEL: c_uint = 200u32

Fill character is ASCII DEL (0177).

If unset, fill character is ASCII NUL (‘\0’). (Not implemented on Linux.)

Source

pub const NLDLY: c_uint = 400u32

Newline delay mask. Values are NL0 and NL1.

[requires _BSD_SOURCE or _SVID_SOURCE or _XOPEN_SOURCE]

Source

pub const NL0: c_uint = 0u32

NLDLY: Newline type 0_.

Source

pub const NL1: c_uint = 400u32

NLDLY: Newline type 1.

Source

pub const CRDLY: c_uint = 3_000u32

Carriage return delay mask. Values are CR0, CR1, CR2, or CR3.

[requires _BSD_SOURCE or _SVID_SOURCE or _XOPEN_SOURCE]

Source

pub const CR0: c_uint = 0u32

CRDLY: Carriage-return delay type 0.

Source

pub const CR1: c_uint = 1_000u32

CRDLY: Carriage-return delay type 1.

Source

pub const CR2: c_uint = 2_000u32

CRDLY: Carriage-return delay type 2.

Source

pub const CR3: c_uint = 3_000u32

CRDLY: Carriage-return delay type 3.

Source

pub const TABDLY: c_uint = 14_000u32

Horizontal tab delay mask.

Values are TAB0, TAB1, TAB2, TAB3 (or XTABS, but see the BUGS section).

A value of TAB3, that is, XTABS, expands tabs to spaces (with tab stops every eight columns).

[requires _BSD_SOURCE or _SVID_SOURCE or _XOPEN_SOURCE]

§BUGS

On the Alpha architecture before Linux 4.16 (and glibc before glibc 2.28), the XTABS value was different from TAB3 and it was ignored by the N_TTY line discipline code of the terminal driver as a result (because as it wasn’t part of the TABDLY mask).

Source

pub const TAB0: c_uint = 0u32

TABDLY: Horizontal-tab delay type 0.

Source

pub const TAB1: c_uint = 4_000u32

TABDLY: Horizontal-tab delay type 1.

TABDLY: Horizontal-tab delay type 2.

Source

pub const TAB3: c_uint = 14_000u32

TABDLY: Horizontal-tab delay type 3.

Source

pub const BSDLY: c_uint = 20_000u32

Backspace delay mask. Values are BS0 or BS1.

(Has never been implemented.)

[requires _BSD_SOURCE or _SVID_SOURCE or _XOPEN_SOURCE]

Source

pub const BS0: c_uint = 0u32

Backspace-delay type 0.

Source

pub const BS1: c_uint = 20_000u32

Backspace-delay type 1.

Source

pub const VTDLY: c_uint = 40_000u32

Vertical tab delay mask. Values are VT0 or VT1.

Source

pub const VT0: c_uint = 0u32

VTDLY: Vertical-tab delay type 0.

Source

pub const VT1: c_uint = 40_000u32

VTDLY: Vertical-tab delay type 1.

Source

pub const FFDLY: c_uint = 100_000u32

Form feed delay mask. Values are FF0 or FF1.

[requires _BSD_SOURCE or _SVID_SOURCE or _XOPEN_SOURCE]

Source

pub const FF0: c_uint = 0u32

FFDLY: Form-feed delay type 0.

Source

pub const FF1: c_uint = 100_000u32

FFDLY: Form-feed delay type 1.

Source

pub const XTABS: c_uint = 14_000u32
