You should be able to pass 2 integers (if it's a 'double or just 
one if it's a 'single), then do the float->integer (by doing a * 
100 e.g.). Probably fun to code. :-)

But you said they must be passed via the FPU?
Dockimbel
29-Jun-2011
[2627]
Right, if you want them in a variable. What I was proposing here 
is to split them from the stack by declaring 2 integers, so that 
the float gets stored in 2 arguments (supposing it is a double).

If cdecl functions pass them on the stack, they may be shuffled between 
them
Dockimbel

The stack order for cdecl and stdcall (used by Red/System) is the 
same.

Almost everything needs floats... better to wait for proper implementation.
Dockimbel

Well, it depends what are the boundaries of your "everything". From 
my own experience, except for 2D/3D and scientific calculations, 
they are rarely needed.

Well, you need it for music and graphics. That's almost everything 
for me. I was checking the FMOD binding, and it's not so bad... at 
least if you don't need to change volume or some more advanced effects:)
Is this useful? http://en.wikibooks.org/wiki/X86_Disassembly/Floating_Point_Numbers

It is another source to confirm that cdecl/stdcall both pass floating 
point arguments via the normal stack :)

Got cURL to read a website and print it:
curl-begin curl-global-all
session: curl-new-session
curl-set session curl-set-upload?  as variant! no
curl-set session curl-set-url  as variant! "http://rebol.com"
curl-do session
curl-end-session session
curl-end
Not as concise as READ "http://rebol.com"but we'll get there

Added a higher level interface that reduces that to
curl-begin
session: curl-new-session
curl-read session
curl-do session "http://rebol.com"
curl-end-session session
curl-end

They say it's a man year work to port it
In any case, I'm not going to do it
But I can upload a file to FTP now
That's direct from disk, so large files can be uploaded without using 
much memory

Can you do multiple uploads concurrently?
Kaj
1-Jul-2011
[2646x3]
No, I can upload one file from disk exclusively. The binding is two 
days old
For multiple concurrent uploads before next week, use my R3 binding
Of course, if you use the 0MQ binding in combination with the cURL 
binding, you can do multiple concurrent uploads from disk only
Kaj

I've implemented a callback framework and used that to implement 
sending a data block from memory, instead of direct from a file
Dockimbel
2-Jul-2011
[2650]
So callbacks are working fine? No more issues?
Kaj
2-Jul-2011
[2651]
A callback used internally by cURL is fine, yes, on Linux. We'll 
see what a progress callback does with trying to print floats
Dockimbel
2-Jul-2011
[2652]
Are you using a version of Red/System that includes my deeper fix 
for callbacks from 2011-06-30 (commit log: Merge branch 'callbacks-cconv')?
Kaj
2-Jul-2011
[2653x2]
If it was committed before the last few hours, I have it
Is that not in the trunk branch? Then I don't have it
Dockimbel
2-Jul-2011
[2655]
I have merged it in main branch 2 days ago.
Kaj
2-Jul-2011
[2656x2]
Two days seems like a long time ago. :-) If that was the final fix 
for 0MQ on Linux, then I already had it
But that was earlier, wasn't it? Then I have only tested the latest 
callbacks with cURL
Dockimbel
2-Jul-2011
[2658]
Right, it was the final fix for callbacks (for the 0MQ issue).

Kaj: we have decided to replace the "struct" and "pointer" by "declare". 
Please read this post: http://groups.google.com/group/red-lang/browse_thread/thread/9c407676e2335919?hl=en
I will be waiting for you to upgrade your bindings before making 
the announcement (hope we can do it tomorrow). I have some things 
to add in the specification and red-lang.org site to dust off in 
the meantime (well, tomorrow would be nice ;-)).
Kaj

I just checked that all the bindings still work with the current 
Red, so the syntax should be the only thing left to change
Dockimbel
3-Jul-2011
[2662]
Ok, if I merge it now with the main branch, can you make the changes 
shortly after?
Kaj
3-Jul-2011
[2663]
Definitely
Dockimbel
3-Jul-2011
[2664x5]
I will wait until tomorrow to make the announcement anyway.
Ok, doing the merge...
Merged.
Going to bed now, will update the web site tomorrow and post an announcement 
on the blog.
(tomorrow => later today)

Ehm, my bindings still work :-)
I only had to make a few changes to the example scripts
This either exposes my preparations for thread safe code, or the 
fact that I haven't written any substantial applications yet :-)
I've extended the read function in the cURL binding to store a file 
being received directly to disk, instead of just printing it
Like sending directly, this has very low memory use
Kaj

I've confirmed that the Empty and Hello examples still run on Syllable, 
but the cURL binding currently segfaults
