Struct axsignal::SignalHandler

pub struct SignalHandler {
    pub handlers: [Option<SigAction>; 64],
}

处理所有信号的结构

Fields

handlers: [Option<SigAction>; 64]

handlers[i] stands for the handler of signal i+1

Implementations

impl SignalHandler

pub fn new() -> Self

新建一个信号处理函数

pub fn clear(&mut self)

清空信号处理模块

会在exec时清空

pub fn get_action(&self, sig_num: usize) -> Option<&SigAction>

To get the action of a signal with the signal number

pub unsafe fn set_action(&mut self, sig_num: usize, action: *const SigAction)

设置信号处理函数

Safety

传入的action必须是合法的指针
