100 
 *  This function maps variable memory pool IDs to variable memory pool

 *  then it returns the variable memory pool control pointer which maps
103 
 *  to ID and location is set to OBJECTS_LOCAL.  if the variable memory
104 
 *  pool ID is global and resides on a remote node, then location is set
105 
 *  to OBJECTS_REMOTE, and the variable memory pool is undefined.  Otherwise,
106 
 *  location is set to OBJECTS ERROR and the variable memory pool is undefined.
107 
 *
108 
 *  Input parameters:
109
