Member Function Documentation

init()

auto cbdc::rpc::kqueue_event_handler::init ( ) -> bool

overridevirtual

Initializes the event handler.

Returns

true if initialization succeeded.

Implements cbdc::rpc::event_handler.

Definition at line 18 of file kqueue_event_handler.cpp.

poll()

auto cbdc::rpc::kqueue_event_handler::poll ( ) -> std::optional<std::vector<event>>

overridevirtual

Wait for events on tracked file descriptors.

Blocks until at least one event is available, or the timeout expires.

Returns

list of events, or std::nullopt if there was an error during polling.

Implements cbdc::rpc::event_handler.

Definition at line 70 of file kqueue_event_handler.cpp.

register_fd()

void cbdc::rpc::kqueue_event_handler::register_fd ( int fd, event_type et )

overridevirtual

Registers a file descriptor to track for events.

Parameters

fd	file descriptor.
et	event type.

Implements cbdc::rpc::event_handler.

Definition at line 33 of file kqueue_event_handler.cpp.

set_timeout()

void cbdc::rpc::kqueue_event_handler::set_timeout ( long timeout_ms )

overridevirtual

Sets the timeout for poll to return even if there are no events.

Parameters

timeout_ms

timeout in milliseconds. 0 to disable timeout.
