If with directly means 'without calling any C function' you can
use inline assembly:
```D
version(linux)
void rt_sigreturn() {
version(D_InlineAsm_X86_64) asm {
naked;
mov EAX, 15;
syscall;
}
}
```
This is the most "direct" way possible. However I should probably
not mess with assembly at this point and use the built-in D
header file for unistd. Thanks a lot for your time tho, have a
great day!

From my understanding, this is binding from C so at least I don't have to make them on my own. Thanks a lot for your time, have an amazing day!

I just wonder if I'm able to do system calls directly from D or If I have to create bindings from "unistd.h" from C
