SHGetValue:

DWORD SHGetValue(          HKEY hkey,
    LPCTSTR pszSubKey,
    LPCTSTR pszValue,
    LPDWORD pdwType,
    LPVOID pvData,
    LPDWORD pcbData
);

That sounds like it would work nicely.  Is there an api for that which I =
am
unaware of or do you have to loop over the registry items at
/HKEY_LOCAL_MACHINES\SYSTEM\CurrentControlSet\Control\Session=20
Manager\Environment
That seems to be where the system wide environment variables are set.
I suppose that I could then call setenv on each entry.  Once that is=20
done, the
rest of the code should work as is...

My system also has settings in the following two registry folders:
/HKEY_LOCAL_MACHINES\SYSTEM\ControlSet001
/HKEY_LOCAL_MACHINES\SYSTEM\ControlSet002

But I assume that the CurrentControlSet is the one we would want...
