Teletype 设备相关 ioctl 命令，用于控制终端（如串口、TTY）行为。

Variants

TCGETS = 21_505

获取当前串口设置（termios 结构体）

TCSETS = 21_506

立即设置串口配置（termios 结构体）

TCSETSW = 21_507

等待输出缓冲区刷新后再设置串口配置

TCSETSF = 21_508

刷新输入输出缓冲区后设置串口配置

TCGETA = 21_509

获取当前串口设置（termio 结构体）

TCSETA = 21_510

立即设置串口配置（termio 结构体）

TCSETAW = 21_511

等待输出缓冲区刷新后设置串口配置

TCSETAF = 21_512

刷新输入输出缓冲区后设置串口配置

TIOCGPGRP = 21_519

获取当前终端的前台进程组 ID

TIOCSPGRP = 21_520

设置当前终端的前台进程组 ID

TIOCGWINSZ = 21_523

获取终端窗口大小（通常与 struct winsize 搭配）

TIOCSWINSZ = 21_524

设置终端窗口大小

FIONCLEX = 21_584

取消 close-on-exec 标志（在 exec 执行时文件描述符不会自动关闭）

FIOCLEX = 21_585

设置 close-on-exec 标志（在 exec 执行时自动关闭文件描述符）

FIONBIO = 21_537

设置非阻塞 I/O（rustc 编译器也会用这个 ioctl 命令控制 pipe 行为）

RTCRDTIME = 2_149_871_625

获取 RTC（实时时钟）的当前时间（用于 RTC 设备）

Trait Implementations

impl Debug for TermIoctlCmd

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TermIoctlCmd

fn eq(&self, other: &TermIoctlCmd) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<u32> for TermIoctlCmd

type Error = TryFromPrimitiveError<TermIoctlCmd>

The type returned in the event of a conversion error.

fn try_from(number: u32) -> Result<Self, TryFromPrimitiveError<Self>>

Performs the conversion.

impl TryFromPrimitive for TermIoctlCmd

const NAME: &'static str = "TermIoctlCmd"

type Primitive = u32

type Error = TryFromPrimitiveError<TermIoctlCmd>
