I take it your trying to get the current directory of the active process?
Look at the PROCESS_PARAMETERS (usually at 0x20000) if the peb isn’t null.
This is assuming your in the process’s context.

Thank you for reply. The problem is the driver is a kernel mode DLL called
by other driver. And active process can be arbitrary at the call time. It
looks like I have to manage own environment variables list and just copy
the values from registry at C RTL startup… What do you think? In any case
nobady except me uses this -)

Use the registry. That is the proper way to store any information an
environment would normally hold. Environment variables are by their nature
a user-mode entity and a hold-over from older operating systems.
