tg-signal-defs

Signal definitions for the rCore tutorial operating system.

Overview

This crate provides the fundamental signal definitions used throughout the rCore tutorial kernel, including signal numbers and signal action structures compatible with POSIX-like systems.

Features

• SignalNo enum: Complete set of standard Unix signals (SIGHUP through SIGSYS) plus real-time signals (SIGRT*)
• SignalAction struct: Signal handler configuration with handler address and signal mask
• no_std compatible: Designed for bare-metal kernel environments

Signal Numbers

Standard signals (1-31):

• SIGHUP, SIGINT, SIGQUIT, SIGILL, SIGTRAP, SIGABRT
• SIGBUS, SIGFPE, SIGKILL, SIGUSR1, SIGSEGV, SIGUSR2
• SIGPIPE, SIGALRM, SIGTERM, SIGSTKFLT, SIGCHLD, SIGCONT
• SIGSTOP, SIGTSTP, SIGTTIN, SIGTTOU, SIGURG, SIGXCPU
• SIGXFSZ, SIGVTALRM, SIGPROF, SIGWINCH, SIGIO, SIGPWR, SIGSYS

Real-time signals (32-63):

• SIGRTMIN through SIGRT31

Usage

use tg_signal_defs::{SignalNo, SignalAction, MAX_SIG};

// Create a signal action
let action = SignalAction {
    handler: handler_address,
    mask: 0,
};

// Use signal numbers
let sig = SignalNo::SIGINT;
