Function Documentation

waitImplementation()

std::pair<int, SignalInformation> distortos::ThisThread::Signals::anonymous_namespace{ThisThread-Signals.cpp}::waitImplementation	(	const SignalSet &	signalSet,
		const bool	nonBlocking,
		const TickClock::time_point *const	timePoint
	)

Implementation of distortos::ThisThread::Signals::wait(), distortos::ThisThread::Signals::tryWait() and distortos::ThisThread::Signals::tryWaitUntil().

Warning

This function must not be called from interrupt context!

Parameters

[in]	signalSet	is a reference to set of signals that will be waited for
[in]	nonBlocking	selects whether this function operates in blocking mode (false) or non-blocking mode (true)
[in]	timePoint	is a pointer to time point at which the wait for signals will be terminated, used only if blocking mode is selected, nullptr to block without timeout

Returns

pair with return code (0 on success, error code otherwise) and SignalInformation object for accepted signal; error codes:

• EAGAIN - no signal specified by signalSet was pending and non-blocking mode was selected;
• ENOTSUP - reception of signals is disabled for current thread;
• error codes returned by internal::Scheduler::block() (for blocking mode without timeout) / internal::Scheduler::blockUntil() (for blocking mode with timeout);
• error codes returned by internal::SignalsReceiverControlBlock::acceptPendingSignal();
