At first QueryStatus call, output is written to Irp->AssociatedIrp.SystemBuffer.
Unfortunately, this is also the BattWait buffer.
At return of QueryStatus call, BattWait buffer has been modified, so
following code can't use it anymore.
Fix memory overwrite by copying BattWait buffer on the stack.
There is no need to compile our DLLs as shared libraries since we are
managing symbols exports and imports through spec files.
On my system, this reduces the configure-time by a factor of two.
- Add missing parameter to a DPRINT.
- Print pointers using %p instead of %x.
- Move all executable code behind a functions initial DPRINT.
- Do not use non-trivial initializers.
- Check for NULL instead of using !.
- Add missing parentheses.
