Member Function Documentation

◆ make_sigset()

sigset_t geopm::POSIXSignalImp::make_sigset ( const std::set< int > & signal_set ) const

overridevirtual

Create a sigset_t from a set of signal numbers.

Exceptions

geopm::Exception upon EINVAL

Parameters

signal_set [in]: Set of all signal numbers to add to the sigset.

Returns: A sigset_t that is zeroed except for specified signals

Implements geopm::POSIXSignal.

◆ reduce_info()

POSIXSignal::m_info_s geopm::POSIXSignalImp::reduce_info ( const siginfo_t & info ) const

overridevirtual

Extract the signal number, signal value integer and sending PID from a siginfo_t struct to simplify mock data.

Parameters

info	[in]: see sigaction(2) man page

Returns: m_info_s reduced information set from siginfo_t struct

Implements geopm::POSIXSignal.

◆ sig_action()

void geopm::POSIXSignalImp::sig_action	(	int	signum,
		const struct sigaction *	act,
		struct sigaction *	oldact
	)		const

overridevirtual

Wrapper for sigaction(2) that converts errors into Exceptions.

Exceptions

geopm::Exception upon EFAULT, EINVAL

Warning: The Linux API sigaction(2) does not properly implement error checking, so this function checks for EFAULT if act or oldact are nullptr

Remarks: See documentation for sigaction(2) about parameters.

Implements geopm::POSIXSignal.

◆ sig_proc_mask()

void geopm::POSIXSignalImp::sig_proc_mask	(	int	how,
		const sigset_t *	sigset,
		sigset_t *	oldset
	)		const

overridevirtual

Wrapper for sigprocmask(2) that converts errors into Exceptions.

Exceptions

geopm::Exception upon EFAULT, EINVAL

Remarks: See documentation for sigprocmask(2) about parameters and return value.

Implements geopm::POSIXSignal.

◆ sig_queue()

void geopm::POSIXSignalImp::sig_queue	(	pid_t	pid,
		int	sig,
		int	value
	)		const

overridevirtual

Wrapper for sigqueue(3) that converts errors into Exceptions.

Exceptions

geopm::Exception upon EINVAL, ESRCH

Remarks: See documentation for sigqueue(3) about parameters.

Implements geopm::POSIXSignal.

◆ sig_suspend()

void geopm::POSIXSignalImp::sig_suspend ( const sigset_t * mask ) const

overridevirtual

Wrapper for sigsuspend(2) that converts errors into Exceptions.

Exceptions

geopm::Exception upon EFAULT

Remarks: See documentation for sigsuspend(2) about parameters and return value. Except that it doesn't return an error by default.

Implements geopm::POSIXSignal.

◆ sig_timed_wait()

int geopm::POSIXSignalImp::sig_timed_wait	(	const sigset_t *	sigset,
		siginfo_t *	info,
		const struct timespec *	timeout
	)		const

overridevirtual

Wrapper for sigtimedwait(2) that converts errors into Exceptions.

Exceptions

geopm::Exception upon EAGAIN, EINTR, EINVAL

Remarks: See documentation for sigtimedwait(2) about parameters and return value.

Implements geopm::POSIXSignal.

◆ sig_wait_info()

int geopm::POSIXSignalImp::sig_wait_info	(	const sigset_t *	sigset,
		siginfo_t *	info
	)		const

overridevirtual

Wrapper for sigwaitinfo(2) that converts errors into Exceptions.

Exceptions

geopm::Exception upon EAGAIN, EINTR, EINVAL

Remarks: See documentation for sigwaitinfo(2) about parameters and return value.

Implements geopm::POSIXSignal.
