## The ACE\_Sched\_Priority type should be used for platform-

independent thread and process priorities, by convention. int should be used for OS-specific priorities.

## typedef for the \_stat data structure

## Get/set the token rate in bytes/sec.

## Get/set the token bucket size in bytes.

## Get/set the PeakBandwidth in bytes/sec.

## Get/set the latency in microseconds.

## Get/set the delay variation in microseconds.

## Get/set the service type.

## Get/set the maximum SDU size in bytes.

## Get/set the minimum policed size in bytes.

## Get/set the time-to-live.

## Get/set the priority.

## Giving unique ACE scoped names for some important

RTSignal-Related constants. Becuase sometimes, different platforms use different names for these constants.
