Re: [Vala] Creating a binding for a non-glib library and using delegate to map a function pointer

Perhaps I got the point where I was wrong.

Another way to do that is to define the delegate in another vala
source file and include it in the compilation where libfoo.vapi is
used.

So, use the same files described before:

 libfoo.c    [http://pastebin.com/u89bWnib]
 libfoo.h    [http://pastebin.com/kDr91Cfg]
 testfoo.c    [http://pastebin.com/UiZk6BiG]
 test_foo.vala    [http://pastebin.com/6ecJLpic]
 libwrapfoo.vala    [http://pastebin.com/z2JExW4v]
 test_oo_foo.vala    [http://pastebin.com/XiAGk9Ww]

But... use these new ones:

 libfoo.vapi    [http://pastebin.com/HJ2NMzRn]
 use_with_libfoo.vala    [http://pastebin.com/HwNY6d0K]

The I can issue the following commands:

<Use the commands here http://pastebin.com/2dfvzW1s>
And they all go right.

Further, I can issue the following:

And I can code in oo-style without directly reference the old library.
