Detailed Description

Signal handle.

Member Function Documentation

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

Create a signal handle.

Parameters
loopLoop object where this handle runs.
static std::shared_ptr<Signal> wpi::uv::Signal::Create ( const std::shared_ptr< Loop > &  loop)
inlinestatic

Create a signal handle.

Parameters
loopLoop object where this handle runs.
int wpi::uv::Signal::GetSignal ( ) const
inline

Get the signal being monitored.

Returns
Signal number.
void wpi::uv::Signal::Start ( int  signum)

Start watching for the given signal.

Parameters
signumSignal to watch for.
void wpi::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
signumSignal to watch for.
