Of course there is nothing wrong with defining each callback as
a separate function, but then comes the issue of naming them. I
also don't like the way it makes my code look.
I think the best you can do is something like this:
---
auto callback(T, string file = __FILE__, size_t line =
__LINE__)(T handler) {
import std.traits;
__gshared T handler_;
handler_ = handler;
extern(Windows)
ReturnType!T fn(Parameters!T args) {
synchronized return handler_(args);
}
return &fn;
}
void main() {
HWND[] list;
EnumWindows((HWND hwnd, LPARAM lparam) {
list ~= hwnd;
return TRUE;
}.callback(), 0);
writeln(list);
}
