     26  REVISION HISTORY
     27 
     28  Description:
     29  (1) Modified to include the lines...
     30 
     31     #ifdef __cplusplus
     32     extern "C" {
     33     #endif
     34 
     35     #ifdef __cplusplus
     36     }
     37     #endif
     38 
     39  (2) Updated the copyright header.
     40 
     41  Description: Modified to include updated function declaration, which reflects
     42  the combination of the get_tns and tns_setup_filter routines.  Also, moved
     43  pInputStream to be the 2nd parameter, for a slight optimization.
