Shouldn't it be possible to capture a list of users on a windows box by only using the Win32::API module? I attempted this but I am not a C programmer. Where did I go wrong? This code actually causes perl.exe to die with the following error:

The instruction at "0x71c42b8c" referenced memory at "0x00000000". The
+ memory could not be "written".
