Binding to C

[chris <spamoff.danx@ntlworld.com>]

Hi,

I came across the following in libjpeg... what should I map it to?

const char* const* jpeg_message_table

Also does anyone have any advice in general mapping to C.  For the 
jpeg_error_mgr struct, I mapped ptrs to functions to System.Address and 
made the struct a record.  Will this work, or will the corresponding 
type of the struct have to be a System.Address?

package Low_Jpg.Error is

    package C renames Interfaces.C;

    type Jpeg_Error_Mgr is record
       Error_Exit      : System.Address; -- addr of a handler
       Emit_Message    : System.Address;
       Output_Message  : System.Address;
       Format_Message  : System.Address;
       Reset_Error_Mgr : System.Address;
       Msg_Code        : C.Int;
       Msg_Parm        : System.Address;
       Trace_Level     : C.Int;
       Num_Warnings    : C.Long;
    end record;
    pragma Convention (C, Jpeg_Error_Mgr);

end Low_Jpg.Error;
