 2  * Description: locmem.hh
 3  *   Implements LOCMEM which is a derived class of CMS that serves
 4  *   primarily to provide addresses that match when matching buffer
 5  *   names are passed to the constructor. It is useful in allowing
 6  *   control modules to use the same inteface to communicate as would
 7  *   be required if they were not running in the same process even
 8  *   though to use LOCMEM they must be.
