Function Documentation

◆ ReadFastCounter()

absl::StatusOr< FastCounterReading > symbian::api::system::ReadFastCounter ( )

Read the fast counter and its frequency, or a typed OS error.

Availability and resolution depend on the device or emulator profile.

◆ ReadTickCounter()

absl::StatusOr< TickReading > symbian::api::system::ReadTickCounter ( )

Read the native system tick and its period, or a typed OS error.

◆ RequestActiveServiceStop()

absl::Status symbian::api::system::RequestActiveServiceStop	(	std::int32_t	category,
		std::uint32_t	stop_key
	)

Request an active service to stop from another guest thread.

◆ RunActiveService()

absl::Status symbian::api::system::RunActiveService	(	std::int32_t	category,
		std::uint32_t	stop_key,
		const std::function< absl::Status()> &	start,
		const std::function< void()> &	on_stop,
		const std::function< void()> &	on_ready
	)

Run a service on the calling thread's native active scheduler.

Owns a process-local stop property. The start callback runs after scheduler installation and must arm its asynchronous requests before returning. on_ready runs once after the stop signal is armed. on_stop runs when the signal requests shutdown or its subscription fails. Both callbacks and StopActiveService run on the scheduler thread. Another thread can request shutdown through RequestActiveServiceStop. Only one service loop may run per thread; the property category/key must be unique to the app.

◆ StopActiveService()

void symbian::api::system::StopActiveService ( )

Stop the current thread's active service from its event callback.
