RTEMS (Real-Time Executive for Multiprocessor Systems) is a free open source real-time operating sys

/*  Init
 *
 *  This routine is the initialization routine and test code for
 *  global partitions.  It creates a global partition, obtains and
 *  releases a buffer, and deletes the partition.  The partition
 *  is created on node one, and an attempt is made to delete it
 *  by node two.
 *  This routine is the initialization task for this test program.
 *  It is a user initialization task and has the responsibility for creating
 *  and starting the tasks that make up the test.  If the time of day
 *  clock is required for the test, it should also be set to a known
 *  value by this function.
 *
 *  Input parameters:
 *    argument - task argument
 *
 *  Output parameters:  NONE
