Detailed Description

Paraslash's scheduler.

Designed with KISS in mind. It maintains a list of task structures which is extended when a new task is registered. Each task may define a pre_monitor function which is called from the scheduler main loop before it calls poll(2). Similarly, each task must define a post_monitor function which is called after poll(2) returns.

select(2), poll(2).
