Made this a while ago:

Thanks, I had a look. Unfortunately it doesn't compile for my 
use case.
SetWindowsHookEx expects an "extern(windows)" and "nothrow" 
function.
delegate2function does not accept a delegate with

If it is possible to make this coding generic, it would fit 
into

...  does not accept a delegate with extern(windows).

You can fix this by a cast:

alias callbackType = extern (Windows) uint function(void*);     
        
CreateThread(cast(SECURITY_ATTRIBUTES*)null, stackSize, 
cast(callbackType)delegate2function(c), cast(void*)&param, 
(suspended) ? CREATE_SUSPENDED : 0, &Id);

But there seems to be a problem as I can only get parameters to 
pass correctly on dmd x64.
