Re: How to convert these constructs to D?

[Rémy Mouëza]

For the two first ones, I would use an alias:
    alias GetCurrentThreadId pthread_self;
    alias void *  pthread_handler_t;
The third one is a function pointer alias:
    alias void * function (void *) pthread_handler;

For the last one, I am not sure, being rusty with the C preprocessor 
rules. I would use a template function:
    import core.stdc.config : c_long;

    void set_timespec_nsec (T, U) (ref T abstime, U nsec) {
       GetSystemTimeAsFileTime (& abstime.tv.ft);
       abstime.tv.i64 += cast (long) (nsec) / 100;
       abstime.max_timeout_msec = cast (c_long) (nsec /1000000);
    }
Though, with that last one, you lost the ability to get it inlined (but 
there is still the -inline computer switch if performance is a real issue).
As for the type mapping, it seems that:
 - __int64 in C corresponds to long in D
 - long in C corresponds to c_long defined in core.stdc.config.

Don't hesitate to double check all this, I may have written something wrong.

I'm porting some C headers and wondered how would i convert the
following to D:
