task1.c

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

/*  Test_task
 *
 *  This task initializes the signal catcher, sends the first signal
 *  if running on the first node, and loops while waiting for signals.
 *
 *  NOTE: The signal catcher is not reentrant and hence RTEMS_NO_ASR must
 *        be a part of its execution mode.
 *
 *  Input parameters:
 *    argument - task argument
 *
 *  Output parameters:  NONE
