Detailed Description

The SignalHandle handle.

Signal handles implement Unix style signal handling on a per-event loop bases.
Reception of some signals is emulated on Windows.

To create a SignalHandle through a Loop, no arguments are required.

See the official documentation for further details.

Definition at line 34 of file signal.h.

Member Function Documentation

init()

bool uvw::SignalHandle::init

(

)

Initializes the handle.

Returns

True in case of success, false otherwise.

oneShot()

void uvw::SignalHandle::oneShot

(

int

signum

)

Starts the handle.

Same functionality as SignalHandle::start but the signal handler is reset the moment the signal is received.

Parameters

signum

signal()

int uvw::SignalHandle::signal ( ) const

noexcept

Gets the signal being monitored.

Returns

The signal being monitored.

start()

void uvw::SignalHandle::start

(

int

signum

)

Starts the handle.

The handle will start emitting SignalEvent when needed.

Parameters

signum

The signal to be monitored.
