+ REVISION HISTORY
+
+ Description:
+ (1) Modified to include the lines...

+    #ifdef __cplusplus
+    }
+    #endif
+
+ (2) Updated the copyright header.
+
+ Description: Modified to include updated function declaration, which reflects
+ the combination of the get_tns and tns_setup_filter routines.  Also, moved
+ pInputStream to be the 2nd parameter, for a slight optimization.
