+/*  void Shm_get_config( localnode, &shmcfg )
+ *
+ *  This routine initializes, if necessary, and returns a pointer
+ *  to the Shared Memory Configuration Table for the UNIX
+ *  simulator.
+ *
+ *  INPUT PARAMETERS:
+ *    localnode - local node number
+ *    shmcfg    - address of pointer to SHM Config Table
+ *
+ *  OUTPUT PARAMETERS:
+ *    *shmcfg   - pointer to SHM Config Table
+ *
+ *  NOTES:  This driver is capable of supporting a practically unlimited
+ *          number of nodes.
