IMHO, it's an address when level==-1 (ME: 0x0041afd4, 95:0x0051000c)
On level==0 it's set to 0.
In the other cases, the value depends on the Default Printer.
I have seen 213, 257, 294, 297, 319, 401

This will not work.
The first "continue" (ERROR_OUTOFMEMORY-check) leaves the if-case but
goes on in the for-loop.
Using a nested if is IMHO the ugly way.
Initializing "needed" with 0 is the easy way: We do not get an
ERROR_OUTOFMEMORY from win9x and can remove the extra check, but you
told us, that you do not want "needed=(DWORD)-1" to change.
It's not our Fault, that the App, that you want to get working, is so
buggy, that it depends on such an undocumented crap.
Fixing your broken tests is really Time-consuming:
test_DEVMODE failed, when the Printername has more
TCHAR than CCHDEVICENAME (32)
You can see the failing tests on XP in the WRT-Results.
When the Default Printer is on a Server, the Limit is
NT3.51 has more failures:
dmDriverExtra is 0 and dmDevicename is empty.
(dmSpecVersion and dmDriverVersion are also 0)
