Basically the task ID is anything you need. You can then create a hash
table to keep pointers to the task specific data global in your system.
This will require dynamic handling of the table and also checking if the
table contains task data and creating them if necessary. Task_Attributes
provides an alternative which might appear more usable in an embedded or
real-time system: statically allocated data, faster data access (no hash
table search needed) etc.
