More Florist.

More Florist.

Well, everythings compiled and linked properly.

I can do just everything else I need with Florist. But I'm running into
trouble here...

type Database_Array is new POSIX.Octet_Array;
type Database_Array_Pointer is access all Database_Array;

function Get_Network_Info_By_Name
      (Name    : POSIX.POSIX_String;
       Storage : Database_Array_Pointer)
     return Network_Info;


Now, setting up the Posix_String is pretty straightforward. But I'm
totally lost on this Database_Array_Pointer business. I've tried about a
zillion different possible combinations and either it wont compile or I
get STORAGE_ERROR at runtime.

No problems with the other stuff. Just this. I give up. 

Any pointers(no pun intended) would be greatly appreciated.

Thanks.

STORAGE ERROR could append if you use external libraries using interfaces
package. 
If so, read the RM, it has a lot of informations about interfaces and how
pass parameters.

Have you tried something like

My_Storage : aliased Database_Array(1 .. 255);

begin
 XXX := Get_Network_Info_By_Name(Name => The_Name_You_Already_Figured_Out,
                                                              Storage =>
My_Storage'unchecked_access);
end;

....or something along those lines...

I just tried that out, and I get some warnings, but that statement does
compile. Havent been able to test it yet though. I'll post on that later.

Alright...here's what I have so far. Still getting Storage_Error. NetDB
is the only place I get it.(Why isn't there a simple "Get_Host_By_Name"
function? It's the most commonly used NetDB function. Why does one have
to parse the thing out of the response generated from the
"Get_Network_Info_By_Name" function? A design flaw?)
All my other procedures work so far. This is the only one that's
chaffing.

with Posix;
with Posix.Sockets.Internet;
with Ada.Text_IO;
procedure lookout is
	package NetSock renames Posix.Sockets.Internet;
	package TIO renames Ada.Text_IO;
	Response : Netsock.Network_Info;	
	URL : Posix.Posix_String := "www.yahoo.com";
	Address : Posix.Posix_String(1..64);
	My_Storage : aliased NetSock.Database_Array(1..255);
	Len : Positive;
begin

	Netsock.Open_Network_Database_Connection(True);
	Response := NetSock.Get_Network_Info_By_Name(Name => URL, 
				Storage => My_Storage'unrestricted_access);
	Address := NetSock.Get_Name(Response);
	Len := Address'length;
	declare
		Addr : String(1..Len);
	begin
		Addr := Posix.To_String(Address);

		-- Just to see what the hell Get_Network_Info_By_Name --
		-- spits back at me. I have no idea what it'll be.	  --
		TIO.Put_Line("Response was"& Addr &".");
	end;
	NetSock.Close_Network_Database_Connection;
end lookout;

Heh. Let the chuckles begin.

Really though.  Does this code make sense?

Well..It is following the POSIX standard so if there is a problem it is in
the standard and (probably) not the
implementation.

Up until now we (I) have been answering your question directly without
knowing what your final goals are.
Perhaps you would be happier using the AdaSockets. I find it a lot easier to
use and more "Ada like" v.s. the
POSIX binding.

http://www.rfc1149.net/devel/adasockets

Of course if there is some reason you have to use florist then this is not
the right choice.

I have been using Adasockets in the past. My goal right now is just to
get familiar with Florist.

Adasockets is easier...but I also wanna know Florist.

But thanks for the help. I think I just about got it figured out. I'll
post up my answer once it works.

What are you trying to accomplish? A "normal" DNS query?

Does FLORIST claim to be a conforming POSIX/Ada implementation?  If
not, I'd strongly prefer that it not imply conformance.

So either say it's "conforming" (which is clearly defined by the
standard), or say that it is "patterned on" or words to that effect
that make it clear that it is not claiming or implying conformance.
