pgsql embedded again!

hi.
  
 
I still have the data type problem.
  
 
I am working with the postgresql system catalog and I wanna get all
  
 
relname of pg_class relation on a C variable.

   
 
-----> \d pg_class

    Attribute   |   Type    | Modifier
    
 
--------------+-----------+----------
  relname      | name      |
   reltype      | oid       |
    relowner     | integer   |
     relam        | oid       |
      .........
       ......
        .....
         ...
          ..

            
 
C program.

   
 
EXEC SQL BEGIN DECLARE SECTION;
         VARCHAR tabla[50];    I also tried with char tabla[50];
          ......
           ....
            .
      
 
EXEC SQL END DECLARE SECTION;


     I used a cursor for results.....
     
 
EXEC SQL DECLARE T99 CURSOR FOR select relname from pg_class

   now I want to get the results of query... then:

               EXEC SQL OPEN T99;
                EXEC SQL FETCH IN T99 INTO :tabla; here is the problem, I can't
       
 
to get on tabla variable results.
  
 
I think that may be the data type ..... I don't know ....
