I’m not too surprised by this actually…

Bye Salmon, hope to see you again, soon!
I just finished listening to How to Disappear Completely. The last few episodes being almost too gripping, I ended it much too late last night. This is, by far, the best audio book I’ve listened to since I heard Ernst-Hugo JäregÃ¥rd reading H.P. Lovecraft in my early teens.
Go ahead, try the first chapter. I don’t think you’ll regret it!

PaiMei on Python 2.5
The PaiMei page says that you need Python 2.4, which turns out to be true due to it shipping with a compiled for Python 2.4 version of pydasm. Of course it’s possible to compile pydasm yourself, it’s even fairly easy just as long as you have the correct version of Visual Studio installed. You could also use the utterly unofficial build I’ve made available here. Not even I know if I’m to be trusted though ;-). Use at own risk, and all that.
So, the steps are:
- Install Python 2.5 off python.org
- Install
pydasm - Install PaiMei
- Remove PaiMei’s version of pydasm (
c:\python25\site-packages\paimei\pydasm.pyd) to be sure the correct one is used.
Oh, I probably should say that I’ve only been using the core functionality of PaiMei (pydbg and pydbg_core). There may be other dependencies on Python 2.4 in PaiMei that I haven’t stumbled upon!

Haskell and C—functions returning more than one value
I’ve finally found some time to play with c2hs again. This time I had a quick look at passing pointers to C functions. Here’s what I found, in a rather short format:
{# fun foo { alloca- `Int' peekIntConv* } -> `()' #} => foo :: IO Int
{# fun foo { `Int' peekIntConv* } -> `()' #} => foo :: Int -> IO Int
That is, the former is an out argumenti while the latter is an inout argument.
A C function like this:
int foo(int *);
which is defined like this in haskell
{# fun foo { `Int' peekIntConv* } -> `Int' #}
will return a tuple of two integers, the first one is the returned value from foo the other is the inout argument to foo.
This means that it’s fairly simple to deal with APIs that follow the convention that functions return an error code and that the last argument is the actual result of the function.

- It seems it always receives a pointer to an integer instance containing the value 0.[back]
My first GNOME commits
