Detailed Description

C++ wrapper facade for the sigaction struct.

Constructor & Destructor Documentation

ACE_Sig_Action() [1/9]

ACE_Sig_Action::ACE_Sig_Action

(

)

Default constructor. Initializes everything to 0.

ACE_Sig_Action() [2/9]

ACE_Sig_Action::ACE_Sig_Action	(	ACE_SignalHandler	handler,
		sigset_t *	sigmask = nullptr,
		int	flags = 0 )

Assigns the various fields of a sigaction struct but doesn't register for signal handling via the sigaction function.

ACE_Sig_Action() [3/9]

ACE_Sig_Action::ACE_Sig_Action	(	ACE_SignalHandler	handler,
		const ACE_Sig_Set &	sigmask,
		int	flags = 0 )

Assigns the various fields of a sigaction struct but doesn't register for signal handling via the sigaction function.

ACE_Sig_Action() [4/9]

ACE_Sig_Action::ACE_Sig_Action	(	ACE_SignalHandler	handler,
		int	signum,
		sigset_t *	sigmask = nullptr,
		int	flags = 0 )

Assigns the various fields of a sigaction struct and registers the handler to process signal signum via the sigaction function.

ACE_Sig_Action() [5/9]

ACE_Sig_Action::ACE_Sig_Action	(	ACE_SignalHandler	handler,
		int	signum,
		const ACE_Sig_Set &	sigmask,
		int	flags = 0 )

Assigns the various fields of a sigaction struct and registers the handler to process signal signum via the sigaction function.

ACE_Sig_Action() [6/9]

ACE_Sig_Action::ACE_Sig_Action	(	const ACE_Sig_Set &	signalss,
		ACE_SignalHandler	handler,
		const ACE_Sig_Set &	sigmask,
		int	flags = 0 )

Assigns the various fields of a sigaction struct and registers the handler to process all signalss via the sigaction function.

ACE_Sig_Action() [7/9]

ACE_Sig_Action::ACE_Sig_Action	(	const ACE_Sig_Set &	signalss,
		ACE_SignalHandler	handler,
		sigset_t *	sigmask = nullptr,
		int	flags = 0 )

Assigns the various fields of a sigaction struct and registers the handler to process all signalss via the sigaction function.

default

ACE_Sig_Action() [9/9]

ACE_Sig_Action::ACE_Sig_Action ( ACE_Sig_Action && )

default

~ACE_Sig_Action()

ACE_Sig_Action::~ACE_Sig_Action

(

)

Default dtor.
