* polling slot objects. This slot list represents the Polling Sequence Table

|
||||
* maintain a list of polling slot objects.
|
||||
* This slot list represents the Polling Sequence Table in software.
|
||||
*
|
||||
* Each polling slot contains information to indicate when and
|
||||
* which device handler shall be executed within a given polling period.
|
||||
* The sequence is then executed by iterating through this slot list.
|
||||
* Handlers are invoking by calling a certain function stored in the handler list.
|
||||
* which executable object shall be executed within a given polling period.
|
||||
* When adding a slot, a pointer to the executing task, a pointer to the
|
||||
* executable object and a step number can be passed. The step number will be
|
||||
* passed to the periodic handler.
|
||||
* The sequence is executed by iterating through the slot sequence and

* executing the executable object in the correct timeslot.
