Embedded SQL in 'C' (cursors)

Does anyone know how to open a cursor for 'C" ..?

I have checked the previous postings but cannot locate the proper syntax

here is a snipit :

void ShowTable_type(){
  EXEC SQL BEGIN DECLARE SECTION;
  char *Atid; // variables to retrieve the table info
  char *Adesc;
  EXEC SQL END DECLARE SECTION;
  EXEC SQL CONNECT 'nathan';
  EXEC SQL DECLARE lets_get_tid CURSOR FOR
    SELECT type.tid;
  printf("Choose the TID to delete\n\n<TID> \n");
  do{
    EXEC SQL OPEN lets_get_tid;

     EXEC SQL FETCH lets_get_tid INTO  //line 255
      :Atid;

    printf("%s",Atid);
  }while(SQLCODE != SQLEND);
  EXEC SQL CLOSE lets_get_tid;
}

What am  I doing wrong ..? here what happens when I rund ecpg :

ecpg  4sql.c -o 4comp.c
4sql.c:124: parse error
make: *** [sql] Error 255

Please if anyone has any ideas please let me know.

Thank you

Nathan
