I want to use external or C function.
It used only one time from one D function.
I want do declare C function inside D function.
I don't want to declare C function in global scope.

Is my wish correct?
Reduced code:



extern (C) int getch();
void main() {
  getch();
}
//compiled OK



void main() {
  extern (C) int getch();
  getch();
}
//Error 42: Symbol Undefined __D4test4mainFZ5getchUZi

you can use local import


cfun.d:
module cfun;
extern (C) int getc();

main.d:
module main;
void main() {
    import cfun;
    getc();
}
