Function register_signal_handler 

pub fn register_signal_handler(num: c_int, handler: SignalHandler) -> Result<()>

Register the signal handler of signum.

Safety

This is considered unsafe because the given handler will be called asynchronously, interrupting whatever the thread was doing and therefore must only do async-signal-safe operations.

Arguments

• num: the signal number to be registered.
• handler: the signal handler function to register.

Examples

extern crate vmm_sys_util;
use vmm_sys_util::signal::{register_signal_handler, SignalHandler};

extern "C" fn handle_signal(_: c_int, _: *mut siginfo_t, _: *mut c_void) {}
register_signal_handler(0, handle_signal);
