/* The Real-Time section...
 * 
 * This section attempts to guarantee that the MatPLc module works
 * under Real-Time constraints. Whether these constraints are hard or soft
 * will mostly depend on the underlying OS. 
 * In any event, the MatPLC simply tries to lock all memory into RAM
 * (if memlock = 1 is chosen in the config file), and
 * to set the apropriate scheduling priority, along with the SCHED_FIFO
 * scheduling policy if a priority > PRIORITY_MIN is chosen.

   * essentially checking whether the OS we are currently using
   * supports the mlockall() function, and if not, abort the MatPLC
   * setup process right now, rather than let the seting up process
   * continue to completion, and have the modules produce an error
