After all, you need to learn something. ...I take it you are a C/C++ programmer - otherwise you would not create a string wich is one char larger then actualy needed. ...for i in word'range loop ...Ada "string" is "char []" and "Ada.Strings.Unbounded" is "std::string". And you would not use operator + () on a char [], would you? So its: - Fri, Dec 31 2004 8:04 am 3 messages, 2 authors http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/5ed7b28464be2e1a Pointer address - 2 new ----------------------- The code is for some IPC stuff. I'm trying to pass messages to another MS program. You were quite right, I was confused about the address clause. Setting the pointer value instead, as I should have, solved the problem.

But that is not what makes the kernel fat. The problem is that OS should have generic interfaces for all kinds of devices. They should be in. You can try to solve it by declaring "everything is a file": UNIX (tm), or by doing nothing Windows (tm), but in both cases the result is pretty same. I think only a native OO design - Fri, Dec 31 2004 11: 03 am 9 messages, 5 authors http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/b95a522100671708 Return_By_Reference or Return_By_Copy (GNAT bug?) - 2 new --------------------------------------------------------- Consider the following version of the Rosen trick. Should A_Type be returned by reference or by copy? GNAT 3.15p says: by reference; more recent versions of GNAT say: by copy. My understanding is that it should be by reference, because it has a component R_Type that is a return_by_reference type (R_Type is return_by_reference because the full view is limited - Fri, Dec 31 2004 12: 07 pm 2 messages, 2 authors http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/74166d5f7afa0c82 Private area and child packages - 4 new --------------------------------------- ...An ...from ...hidden, ...If ...Something. ...client ...opportunities ...But then how do I know when the access to the Implementation object goes out of scope? It seems to me that I need to either derive from Ada.Finalization. Limited_Controlled or define Something as a smart pointer to Implementation. - Fri, Dec 31 2004 9:55 am 4 messages, 2 authors http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/93d7def3eeefbc26 Possible Ada deficiency? - 10 new --------------------------------- I would like to know if anyone else thinks that the inability to hide private information from child packages is a deficiency in Ada95. I am discussing ways to do this on another thread, (See Private area and child packages), but it seems wrong that one has to go through a bunch of machinations to do something like this.
