sched
Defined in header file:  sched.hh

Description

The class sched is the scheduler of the daemon framework and listens on a given port for incoming tcp requests. As soon as a tcp request has been received it will be accepted and the appropriate socket is given to an idle workerthread. If all workerthreads are busy at this time the scheduler waits until a workerthread becomes idle. No further connections are accepted during this time.

The scheduler is an abstract class with the pure virtual method client() which is responsible for creating workerthreads. When the scheduler is started by calling the method exec() a pool of workerthreads is created which will be set into idle state immediately. In idle state a workerthread does not consume any cpu time.
