Guess it didn't...

Third round, hope this time we get it right, expected output:

EnumProcessModules (PID, name): 3128      proc_info.exe
Module32First (PID, name): 3128           proc_info.exe
GetProcessImageFileName (PID, name): 3128 \Device\HarddiskVolume5\Programming\So

EnumProcessModules (PID, name): 4084      cmd.exe
Module32First (PID, name): 4084           cmd.exe
GetProcessImageFileName (PID, name): 4084 \Device\HarddiskVolume2\WINDOWS\system

WinAPI documentation is too confusing about 32-bits process listing
64-bits modules or process... also there is a lot of functions that do
the same from different approaches that aren't compatibles with
previous version of windows.

(i.e. QueryFullProcessImageName is only available in Vista and Windows
Server "Longhorn")...

Maybe I could code some dynamic loading (like psapi in proc_info) to
workaround this case scenario.

Please let me know the results.
