FYI, I didn't realize this (but just figured it out), C main
*used* to be in druntime, but it's now generated by the
compiler. See here:

True. But it is compiler-dependent. GDC actually still defines
C main in the

Your D programs have multiple layers. There is the C runtime, DRuntime,
and your program code.
The C runtime is at the bottom. When the program
Could you explain what mean C main inside the runtime. I
thought that is only one main is possible. And why it's named
*ะก* main D is not C-translated language.
Same question is about _Dmain -- what is it?
If I will call this() before main? What it will be? Will it run
before main?
Every D program is started as if it were a C program.
Why is so necessary?
What about C++ and other languages? Does they have more then one
main?
Why it's more than one main is needed? Why D apps can't start
with single main?

Depends on the implementation. I believe Visual C++ does. But it is used
like D's to allow it to

It's not actually necessary. You could implement the `_start`
function in your D program. Here's a D program without any C
runtime, D runtime, or main.

Then the extern(C) int main() gets called.
Then the _Dmain gets called.
