hi
I just want to apologize for my English [I use a translator]

i'm looking for information about a month and during this time i haven't found almost anything

but what i found is very old and all the sample code is written in C/C++

i want to ask you to provide me with an example code with explanations written in FASM using the simplest calls from ntdll.dll-ntoskrnl.exe

creating a file , displaying a line on the screen or something like that

please if you have information on this topic,share

i want to say thank you in advance for giving me some of your time and helping me

NTDLL.DLL and related calls are not publicly documented, and are not stable across Windows versions.

Any code you find might work for one version of Windows and no others, or it might work for all current versions, and break on the next release.

Nah, because a lot of DRM/anti-cheat garbage relies on it and Microsoft isn't going to shoot themselves in the foot now. Some of them even do direct syscalls which is quite insane but it is what it is.
