init.c

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

/*  Init
 *
 *  This routine is the initialization routine for this test program.
 *  Other than creating all objects needed by this test, if this routine
 *  is running on node one, it acquires a global semaphore to
 *  force all other tasks to pend.  If running on node two, this task
 *  sleeps for a while, and then deletes two local tasks which are
 *  waiting on a remote message queue or a semaphore.
 *  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
