If your system includes the adaptive partitioning scheduler module, the data for these events includes the partition ID and scheduling flags. For more information about adaptive partitioning, see the Adaptive Partitioning User's Guide.
For more information about thread states, see “Thread life cycle” in the QNX Neutrino Microkernel chapter of the System Architecture guide.
