Ase::USignalSource class

EventLoop source for handler execution.

Base classes

static void raise(int8 signum): Flag a unix signal being raised, this function may be called from any thread at any time.

void add_poll(PollFD*const pfd): Add a PollFD descriptors for poll(2) and check().
void loop_remove(): Remove this source from its event loop if any.
auto may_recurse() const → bool: Indicates if this source may recurse.
void may_recurse(bool may_recurse): Dispatch this source if its running recursively.
auto primary() const → bool: Indicate whether this source is primary.
void primary(bool is_primary): Set whether this source prevents its loop from exiting.
auto recursion() const → bool: Indicates wether the source is currently in recursion.
void remove_poll(PollFD*const pfd): Remove a previously added PollFD.

auto check(const LoopState& state) → bool virtual: Check the source and its PollFD descriptors for dispatching (true return).
auto dispatch(const LoopState& state) → bool virtual: Dispatch source, returns if it should be kept alive.
auto prepare(const LoopState& state, int64* timeout_usecs_p) → bool virtual: Prepare the source for dispatching (true return) or polling (false).
