Looking at the logging and the snippet you pasted, the open flags do not match at all.
Good luck on your endeavors finding the problem, I am not going to play a game of 'find the actual code'.

That test failing on ROS would essentially confirm that a bug exists in ROS in the API call NtOpenFile(). How should it be formally reported if confirmed ? There must be something lost if your test worked in ROS. The only obvious difference between the pseudocode and my test in Delphi would be the ...

I'm currently looking at detecting ROS and activating that workaround in a custom cygwin1.dll since I'm more familiar with that code. Now I just need a clean and accurate way to identify ROS using API calls that exist in Windows and ROS. We don't have an api to detect ROS, precisely to not have peo...

I actually did write a test for this, but since I do not really do much programming in C I did it under a tool I'm more familiar with which was Delphi. The test binary produced different results under Win10 than ROS, but in the end it showed that was not an issue with validation. --blub-- ps: You u...

or find a test like that in the existing test suite

I wonder if someone could help me build a small workaround for this problem. Basically what happens is this.. The library(cygwin) calls NtOpenFile using a path and the call works completely and the application gets back a File Handle. The library then it tries to reopen that same file by calling Nt...

The failure I hit results from how Cygwin emulates the posix functions pread() and pwrite(). Since the Posix definition of those functions requires that the filehandles offset (or file pointer) not be moved so that other processes are unaffected by the use of pread/pwrite, what? do you expect that ...

If you run this in a vm debugging should be a lot easier
Check that your structs / pointers are properly aligned?

And if you can modify the kernel (but for some weird reason not view the logging) you can always change error codes around so you can see which path causes it

indeed.

Hi: I created an VM instance of ReactOS (20210107-0.45.15-dev-1606-g4ca7926) on a Hyper-V Server 2012 R2 host. The VM instance has two NICs, one attached to a network were a DHCP server successfully provides an IP address and default gateway. The other NIC is attached to a static network. On this N...

Hallo allemaal. Ik ben nieuw hier, dus zal ik me eerst even voorstellen. Mijn naam is Bart Kuijer, ben 83 jaar en ik woon in Hardenberg. Ik werk met een Acer Aspire, waarop Windows 10 met Office en Linux Mint Uleyana. Daarnaast wilde ik ReactOS installeren, maar dat lukt me niet. Ik startte op met ...

I think the RAPPS should be forked out from Reactos as a package manager. Sooner or later it will be meaningless as a software that has only ReactOS compatible apps. Splitting it off may widen it's audience and indirectly contribute that it develops faster > it can still be part of the ReactOs proj...

I wondered how the OP could have discovered that virtio is already included in ReactOS builds. I used the search string "site:reactos.org virtio" with the DuckDuckGo web search engine. Unfortunately, the results returned on the first page were not helpful to me. The second link returned w...

I always thought USB-mice are not supported in ReactOS. How do you work. I can't even close a window using keyboard-commands...

My usb mouse works fine in vmware.

You don't have to test every version. Take one from the middle of time. If it works take a newer one (the middle again) and if not, take an older one. I know, I was exaggerating a little bit. Nevertheless, it is a time-consuming process. I will do it, but I don't know, how long it is going to take....
