@Jochen Great! I think we can also use this:

Gotcha now. Via Google there's a bit of variation:
We get -3FFFFFCD from here: https://www.mathsisfun.com/binary-decimal-hexadecimal-converter.html
The idea was great here but didn't work for negative numbers:

The whole shebang is here:

Go easy please, the code is well, pretty gross. :P

The first one on Google? Or is that wrong?

ntStatus = -1073741773 = 0XFF5C28F7, hdlNTOut is 0 so we are in nadaland. Hmmm, what happened to NT_ERROR?

Is there a subset of NTstatus somewhere?

Thank_You for reading this. Modified the code in the question by adding a routine. Hope it helps for readability. But hdlNTOut is still zero. And there is a problem with the typedef reported here (see comment in above typedef):

Gah- knew there was something fishy about it. Joy! Originally spooked by this routine in driver binaries as obsolete:
https://msdn.microsoft.com/en-us/library/windows/hardware/ff561934(v=vs.85).aspx

which "should be replaced by RtlUnicodeStringInit". Got the names messed up. No such statement at the link you provided though.

Absolutely. But in the IDE I'm in the habit of becoming too reliant on the autos. :)

Ah yes I see your point now. I can't believe this was written in 1993, but there you go, it still applies:

Nice diagrams here

This stuff is not for the faint hearted. Will have to learn about Linked Lists then, but I fear it's going to be more than five minutes!

Thanks for the time out to reply Sergey. I guess I should have mentioned this is part of an exercise to Program that can create a long Path:

http://stackoverflow.com/questions/31858373/program-to-create-and-move-a-pathname-with-more-than-260-characters-in-windows
so I'll be wanting to touch the limits. Without being too bullish, something like 1000 * 1000 * Max_Path won't topple the stack?
That's an interesting point on fragmentation: doesn't the free() function work as expected? I always assumed Windows employed routines to defrag it's own heap on a regular basis. Found this

https://bitsum.com/virtual_memory_facts_and_memory_optimizer_scams.php interesting and illustrates your point rather well.

Laurie Stearn 16-Nov-15 22:28pm View

Yes thanks, that's an idea. I read your tutorial, great. It's probably a little beyond the scope of my abilities to directly apply that here. Do you recommend any code samples that delve a little deeper?

Laurie Stearn 10-Oct-15 0:23am View

My attempt at a C version of this method failed. There was a solution, however.

@nvtkrishna: Have you tested this for very long path strings? Once created, these paths may not be easy to remove.
