Summary: Argument types for win32process.GetModuleFileNameEx

Initial Comment:
Hi,

According to the msdn docs, the function
GetModuleFileNameEx can accept NULL as the handle to
the module, in which case it returns the path of the
executable of the process itself, rather than the
module. Here is the direct quote from the msdn doc:

hModule
    [in] Handle to the module. If this parameter is
NULL, GetModuleFileNameEx returns the path of the
executable file of the process specified in hProcess.

and a link to the same doc:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/perfmon/base/getmodulefilenameex.asp

Currently, when trying to give None as second argument
to the function gives me error, "TypeError: an integer
is required". So I am unable to invoke that
functionality of GetModuleFileNameEx using win32all. 

Bug or feature? 

Using win32all 203, iirc. (by the way, is there a quick
way to check which version of win32all I have installed?)

Would appreciate your input on this. Or a workaround on
how to get the process name from process id, without
using this function. :)

Thanks!

Ah, thanks. When i tried that earlier, i had another problem
with my code, and i thought that was caused by the argument
type... So i tried doing the same thing through ctypes, got
same problem, solved it... and now putting 0 instead of None
into win32process.GetModuleFileNameEx works as you say.

so bug can be closed. 
Thank you for quick reply! :)

The handle maps to a Python int. So instead of using None
try 0 then it will work.
