Function set_handler 

pub fn set_handler(
    signal_type: SignalType,
    handler: SignalHandler,
) -> Result<(), SetHandlerError>

Available on Windows and crate feature signals only.

Installs the specified handler for the specified signal.

Example

use interprocess::os::windows::signal::{self, SignalType, SignalHandler};

let handler = unsafe {
    // Since signal handlers are restricted to a specific set of C functions, creating a
    // handler from an arbitrary function is unsafe because it might call a function
    // outside the list, and there's no real way to know that at compile time with the
    // current version of Rust. Since we're only using the write() system call here, this
    // is safe.
    SignalHandler::from_fn(|| {
        println!("You pressed Ctrl-C!");
    })
};

// Install our handler for the KeyboardInterrupt signal type.
signal::set_handler(SignalType::KeyboardInterrupt, handler)?;
