Member Function Documentation

Create() [1/2]

std::shared_ptr< Signal > wpi::net::uv::Signal::Create ( const std::shared_ptr< Loop > & loop )

inlinestatic

Create a signal handle.

Parameters

loop	Loop object where this handle runs.

Create() [2/2]

std::shared_ptr< Signal > wpi::net::uv::Signal::Create ( Loop & loop )

static

Create a signal handle.

Parameters

loop	Loop object where this handle runs.

GetSignal()

int wpi::net::uv::Signal::GetSignal ( ) const

inline

Get the signal being monitored.

Returns

Signal number.

Start()

void wpi::net::uv::Signal::Start

(

int

signum

)

Start watching for the given signal.

Parameters

signum

Signal to watch for.

StartOneshot()

void wpi::net::uv::Signal::StartOneshot

(

int

signum

)

Start watching for the given signal.

Same as Start() but the signal handler is reset the moment the signal is received.

Parameters

signum

Signal to watch for.

Stop()

void wpi::net::uv::Signal::Stop ( )

inline

Stop watching for the signal.
