Already read through https://dlang.org/spec/interfaceToC.html

Is it really the case (that an extern(C) function pointer cannot be
assigned to a D variable)? Or is it a matter of annotating with the
right attributes? If so, how?
Works for me:
import core.stdc.stdio: puts;
auto p1 = &puts;
extern (C) int function(const char* s) p2 = &puts;
If you're trying to assign an `extern (C)` function pointer to an
`extern (D)` one (the default), that cannot work. The compiler would
emit code using D's calling convention, but the called function would
assume C's calling convention.
