* The task status flags may be OR'ed together to form a task's state. The
|
|
* existence of one or more non-zero bits indicates that the task can not be
|
|
* scheduled for execution because of the conditions associated with those
|
|
* bits. The task status flags are divided into four (4) groups as follows:
|
|
*
|
|
* Break flags (bits 0..5) are associated with conditions that require an
|
|
* external entity to permit further execution.
|
|
*
|
|
* Spare flags (bits 6..10) are located between the break and wait flags
|
|
* to allow either set to be extended without impacting the other group.
|
|
*
|
|
* Wait flags (bits 11..27) are associated with operations that the task itself
|
|
* initiated, and for which task execution will resume when the requested
|
|
* operation completes.
|
|
*
|
|
* Monitoring bits (bits 28..31) are reserved for use with task level
|
|
* monitoring.
