Instance Method Detail

def after_fork : Nil #
Description copied from class Crystal::EventLoop::Polling

no parallelism issues, but let's clean-up anyway


[View source]
def after_fork_before_exec : Nil #
Description copied from class Crystal::EventLoop::Polling

reset the mutexes since another thread may have acquired the lock of one event loop, which would prevent closing file descriptors for example.


[View source]
def interrupt : Nil #
Description copied from class Crystal::EventLoop

Tells a blocking run loop to no longer wait for events to activate. It may for example enqueue a NOOP event with an immediate (or past) timeout. Having activated an event, the loop shall return, allowing the blocked thread to continue.

Should be a NOOP when the loop isn't running or is running in a nonblocking mode.

NOTE we assume that multiple threads won't run the event loop at the same time in parallel, but this assumption may change in the future!
