Equeue contains a generic implementation of queues of events of any type, and a
|
|
specific implementation of queues of file descriptor events.
|
|
|
|
The generic module allows to associate an event queue with an event source, and
|
|
one or several event handlers. The event source generates new events that are
|
|
triggered from the outer world. The handlers consume events, but it is allowed
|
|
that handlers also generate events.
|
|
The module for file descriptor events already defines an event source; this
|
|
source watches registered file descriptors and produces events if a descriptor
|
|
wants to deliver data, or if a descriptor is ready to accept data. As in the
|
|
generic module, the handlers consume the events.
|
|
|
|
The concept of engines is suggested to construct event-driven programs in a
|
|
systematic way. There are already a number of basic engines (polling, copying,
|
|
connecting with a network service, accepting connections, SOCKS), and a number
|
|
of operations for engines (sequential execution, synchronization).
|
|
|
|
It is possible to let Equeue cooperate with the event queue implementation of
|
|
Tcl. Now, also the Shell library is included in the Equeue distribution.
