Hi,

ah very interesting:


(*  typedef int (*Iparamcb)(Ihandle* dialog, int param_index, void*
    user_data);   *)

FROM SYSTEM IMPORT ADDRESS ;

TYPE
   Iparamcb = PROCEDURE (VAR dialog: Ihandle; param_index: INTEGER;
                         user_data: ADDRESS) ;

is one interpretation of the C data structure.
It does depend upon how you want to use the parameters.  The above is a
match but so to is:

FROM SYSTEM IMPORT ADDRESS ;

TYPE
   PtrToIhandle = POINTER TO Ihandle;
   
   Iparamcb = PROCEDURE (dialog: PtrToIhandle; param_index: INTEGER;
                         user_data: ADDRESS) ;
